Penthouse Chords

Tetrachord Superimposition Over Common Chord Progressions

By Bruce Arnold — Muse Eek Publishing Inc. — ISBN 978-1-59489-182-3

29 tetrachords. 13 progressions. Every key.

Penthouse Chords takes superimposition beyond triads and trichords to four-note structures — the complete set of 29 tetrachord prime forms, systematically applied over every common chord type across all twelve keys. The next frontier in harmonic vocabulary.

Recommended prerequisite: Sonic Single
Penthouse Chords builds directly on trichord superimposition. Comfort with several trichords over common chord progressions will make the four-note material significantly more accessible. The ear training path is the same — SerialEar trichord fluency transfers directly to tetrachord work.

The Concept

Upper-structure triads give you three notes above the chord. Trichord superimposition (Sonic Single) extends that to any three-note structure from the chromatic scale. Penthouse Chords takes the next step: four-note structures — tetrachords — superimposed over every common chord type.

In pitch-class set theory, four-note structures reduce to 29 distinct prime forms. Each prime form is an interval shape — a specific arrangement of four pitches that sounds the same regardless of transposition. When you practice a tetrachord in all twelve keys, you internalize one shape that works across many harmonic contexts, not twelve separate things.

Why 29?

The 29 tetrachord prime forms divide into three groups based on how they relate to diatonic harmony:

Five come from stacking thirds through the major, melodic minor, harmonic minor, and harmonic major scales — these are the Penthouse Chords themselves. Every dominant 7th, minor 7th, major 7th, minor-major 7th, and diminished 7th chord you have ever played reduces to one of these five prime forms.
Seven come from stacking diatonic fourths through the same scales — the quartal structures that define modern jazz comping.
Seventeen are unreachable by either method. They only appear through chromatic superimposition. These are the frontier.

This book covers all twenty-nine equally, with étude files, chord voicings, and arpeggios for every tetrachord across every chord type and key.

Where to Begin: Three Groups That Bear the Most Fruit

Not all 29 tetrachords are equally accessible as starting points. The book organizes the material into three groups, each with immediately usable results:

The Five Most Important Four-Note Structures

Of the 29 possible tetrachords, five account for every diatonic 7th chord built by stacking thirds through any common scale — major, melodic minor, harmonic minor, and harmonic major. These five are the harmonic skeleton of tonal music. Every dominant 7th, minor 7th, major 7th, and the other common chord types you already play every day reduce to one of them. They are sounds you have been absorbing your whole musical life, now made conscious and systematic. This is where the book begins — and where most players will spend the most productive early practice time.

One of the most useful discoveries the prime form system reveals: several familiar chord types share the same four-note structure. Dominant 7, half-diminished, and minor 6 are all the same tetrachord. Minor-major 7 and augmented major 7 are the same tetrachord. Any superimposition that works over one automatically works over the others — instantly doubling or tripling your harmonic coverage.

The Four-Note Structures That Build Quartal Harmony

A second, smaller group of tetrachords emerges when you stack diatonic fourths rather than thirds through the same scales. These are the structures behind the open, modern sound of McCoy Tyner, Bill Evans’s left hand, and post-bop jazz comping generally. The book covers all of them, including those that require the diminished fourth — an interval that sounds like a major third but is spelled as a fourth, and that gives certain quartal voicings their distinctive edge over altered dominants and harmonic minor contexts.

The Diminished Scale Tetrachord

Before moving into the 17 non-diatonic tetrachords, the book devotes a full chapter and a dedicated étude set to the single tetrachord produced by the diminished scale. Used across its three transpositions, this one structure covers an entire 12-bar blues progression with three different octatonic scales. The Diminished Blues étude is self-contained, immediately musical, and one of the most practical tools in the book.

Structure 1 and Structure 2

Almost every tetrachord appears in the étude files in two versions: S1 and S2. This is because 28 of the 29 prime forms are asymmetric — reading the interval sequence in reverse produces a different set of notes, a different sound, and different harmonic applications.

The best example is Major 7 (0158). S1 is C, Db, F, Ab — tight, chromatic, works over DbΔ7 and Eb-7. S2 is C, E, G, B — the familiar close-position C major 7th voicing. Same prime form. Completely different sounds, working over completely different chord roots.

Getting the structure wrong means the notes clash with the harmony. Getting it right means the superimposition is seamless. The S1/S2 distinction is not a technicality — it is the difference between a tetrachord that fits and one that doesn’t.

The one exception is Diminished 7 (0369): three equal minor thirds produce a palindrome, so S1 = S2. This is also why the diminished 7th chord has only three distinct transpositions in the entire twelve-tone system.

The S1/S2 inversion operation is the same mathematical operation that underlies negative harmony. If you already work with axis reflection and chord mirroring, the S2 of each tetrachord gives you a practiced, systematic vocabulary for the mirror side.

Example Files

Each example below shows one page from a representative étude file, with the first few bars audible as MP3. The complete library — all 29 tetrachords across all 13 progressions and all 12 keys — is included with the book.

Arpeggios — Tetrachord 0127, Structure S1 · 6/8 · All 12 Keys

▶ Score (PDF)
⇓ MIDI
🎵 Listen (MP3)

All four inversions ascending then descending through all twelve keys, in 6/8 time. The arpeggio files build physical command of each tetrachord before applying it to chord progressions. Structure S1 and S2 are in separate files for all asymmetric tetrachords.

Melodic Étude With Rests — Minor-Major 7 (0148), Progression 10 · bⅩ7 bⅦ7 Ⅱ7 Ⅴ7

▶ Score (PDF)
⇓ MIDI
🎵 Listen (MP3)

The Minor-Major 7 tetrachord (0148) over a descending chromatic dominant progression. Random rests break up the constant eighth-note stream, creating a more conversational phrase shape — and revealing whether the material has been truly internalized or just memorized mechanically.

Guitar Chord Étude — Tetrachord 0138, Progression 08 (Drop-2) · Ⅱ7 bⅡ7 ⅠⅠ7 bⅠⅠ7

▶ Score (PDF)
⇓ MIDI
🎵 Listen (MP3)

Drop-2 voicings on the upper four strings over a chromatic descending dominant progression — one of the most common cadential sequences in jazz. All twelve keys. The drop-2 format places all four notes within a four-fret position.

Chord Voicings — Minor 7 (0259), Structure S1 · All 4 Inversions · All 12 Keys

▶ Score (PDF)
⇓ MIDI
🎵 Listen (MP3)

Three bars per key: ascending inversions as quarter notes, peak voicing plus descending, root position whole note. One of the five Penthouse Chords and one of the most common voicings in jazz — here made systematic across all positions and keys.

Diminished Blues — Chord Étude, Key of C · Drop-2 · 36 Bars

▶ Score (PDF)
⇓ MIDI
🎵 Listen (MP3)

Three transpositions of the diminished tetrachord as drop-2 chord voicings over a 12-bar blues, three choruses. Moving between C7, F7, and G7 requires only a half-step shift — a direct consequence of the diminished tetrachord’s unique symmetry. The most immediately usable étude in the book.

Blue Eleven — The 23rd Chord in Practice

Blue Eleven is a composition by Bruce Arnold in the key of G, eleven measures long — a traditional blues with one bar removed. The guitar melody is built entirely from the 23rd chord concept developed by jazz educator Charlie Banacos: three seventh-chord arpeggios stacked in ascending thirds, covering all twelve chromatic pitches.

Each of those three arpeggios is a tetrachord. Together they form a twelve-tone aggregate — three tetrachords that partition all twelve pitch classes with no overlaps. This is the principle at the heart of Chapter 11 of the book, shown here in a real compositional context.

Blue Eleven — Score and Recording

▶ Score (PDF)
🎵 Listen (MP3)

Follow the score and notice how the three seventh-chord arpeggios rotate through their positions as the harmony moves through G7 → C7 → G7 → Bb7 → A7 → Ab7. The complete twelve-note aggregate sits naturally inside a straight-ahead jazz blues.

Recommended Practice Sequence

The book recommends this order — starting with sounds your ear already knows, then moving to increasingly unfamiliar territory:

This course teaches you the five most important Penthouse Chords first — the five tetrachords that account for all diatonic 7th chords. Your ear already knows these sounds. The work is making the superimposition conscious and systematic, in all twelve keys.
Next, The seven quartal tetrachords — These are the open more modern sound of McCoy Tyner and post-bop harmony. Some require the diminished fourth — an interval that sounds like a major third but is spelled as a fourth. The book covers this distinction in detail.
The diminished tetrachord in all three transpositions — the Diminished Blues étude before moving to the other seventeen tetrachords. This establishes the octatonic system as a practical, playable tool.
The remaining seventeen tetrachords — the frontier. These only appear through chromatic superimposition; no diatonic stacking method ever produces them. SerialEar ear training is the recommended companion for this stage.

Frequently Asked Questions

Do I need to complete Sonic Single before starting Penthouse Chords?

A solid foundation with trichord superimposition will make the material significantly more accessible, but it is not a strict prerequisite. If you are comfortable with your seventh chord arpeggios and have done some ear training work, you can start with the five Penthouse Chords directly. The frontier material — the seventeen non-diatonic tetrachords — will require more ear training work regardless of background.

What is the difference between S1 and S2?

S1 uses the prime form as written — the most compact interval arrangement reading upward. S2 is the inversion: reading the interval sequence in reverse produces a genuinely different set of notes that works over different chord roots. For the Major 7 tetrachord, S1 is the tight chromatic voicing and works over different chord roots than S2 — the familiar close-position major 7th voicing. Both are practiced separately throughout the étude files, and the book includes full compatibility tables for each structure.

Why does the Diminished 7 tetrachord (0369) only have three transpositions?

Because all three of its intervals are equal minor thirds. That perfect symmetry means every fourth semitone returns to an equivalent structure — there are only three distinct diminished 7th chords in the entire twelve-tone system. It is also the only tetrachord where S1 = S2, for the same reason: reversing the interval sequence produces the same sequence. This symmetry is what makes the Diminished Blues étude work so efficiently — one tetrachord covers the whole progression.

What instrument is this written for?

The melodic études and arpeggios are instrument-agnostic, notated in treble clef. The chord études and voicings are most directly useful for guitarists and pianists. Guitar-specific drop-2 voicings on the upper four strings are provided separately from the standard voicings. All MIDI files work with any DAW or MIDI player.

How does the 23rd chord system relate to this book?

The 23rd chord, developed by Charlie Banacos, stacks three seventh-chord arpeggios in ascending thirds to cover all twelve chromatic pitches. Each arpeggio is a tetrachord. Together they form a three-tetrachord aggregate — one of 293 possible ways to partition all twelve pitch classes into three non-overlapping four-note sets. Chapter 11 covers this system in full, with exercises for all eight chord types.

What is the Diminished Blues étude?

A 12-bar blues using three transpositions of the diminished tetrachord — one for each dominant chord in the progression. Because of its unique symmetry, moving between C7, F7, and G7 requires only a half-step shift of the same voicing. Available in melodic, melodic-with-rests, and drop-2 chord versions, in all twelve keys. It is the most immediately usable étude in the book and a good place to start.

A Three-Century Pedagogical Lineage

The principle of hearing music from a tonal center was passed forward through three centuries of teaching. The core chain: Scarlatti → Porpora → Haydn → Beethoven → Czerny → Liszt → Siloti → Vengerova → Graffman → Banacos → Bruce Arnold.

Bruce Arnold studied with Charlie Banacos and Jerry Bergonzi. Banacos’s insistence on hearing every note in relationship to a single key center — and his development of the 23rd chord system at the heart of Chapter 11 — runs through every page of this book.

Symmetric and Asymmetric Trichord Pairs Over Common Chord Progressions

By Bruce Arnold — Muse Eek Publishing Inc. — ISBN 978-1-59489-180-9

Two trichords. One hexachord. Every key.

Sonic Twins takes trichord superimposition to the next level — pairing two trichords that together cover six notes of the chromatic scale, forming a hexachord with specific harmonic properties over each chord type. Systematic, audible, and immediately musical. This course contains all usable triad pairs but expands to include all 3 note combination that are not built in 3rds.

Recommended Prerequisite: Sonic Single
Sonic Twins assumes some fluency with individual trichord superimposition or triad pairs combinations. Completing Sonic Single is a good idea but not required. This course will develop a solid foundation with all relevant trichords across multiple progressions — so if you want to take a deep dive into the modern concept of moving back and forth between to groups of three notes. This course is exactly what you need.

The Concept

In Sonic Single, you work with one trichord at a time — learning to hear and execute each three-note structure over each chord type in every key. Sonic Twins takes the next step: instead of one trichord at a time, you work with pairs.

A trichord pair is two trichords chosen so that together they cover six distinct pitch classes — a hexachord. It is the same concept as two triad pairs but expands to include any 3 note combination. The two trichords share no notes. When you alternate between them over a chord progression, you produce a six-note sound world that is harmonically complete, intervalically rich, and recognizably different from any single trichord.

Symmetric and Asymmetric Pairs

Symmetric pairs use two transpositions of the same trichord prime form. The two trichords share no notes but have identical interval structures. Their combined hexachord is inversionally symmetric — it maps onto itself under inversion. Sonic Twins covers 69 symmetric pairs across all twelve trichord types.

Asymmetric pairs combine two different trichord prime forms. The hexachord produced may or may not be inversionally symmetric. Sonic Twins covers 259 asymmetric pairs. Together the 328 pairs represent the complete curated set of musically useful trichord pairings across all eight chord types.

The 249 Symmetric Hexatonic Pairs

Within the symmetric pairs, 249 produce inversionally symmetric hexatonic scales when considered over specific chord types. The table below shows the count of symmetric hexatonic pairs available for each trichord type over each chord type:

Trichord	Maj7	min7	dom7	7sus4	minMaj7	min7b5	dim7	Maj7#5	Total

Trichord Pairs in Practice: Compositions

The fastest way into the sound of a trichord pair is to listen to music built from it. The compositions below use specific trichord pairs consistently throughout — the melodies and harmonies derive from the two trichords moving through the chord changes.

015 — Entanglement

▶ Score (PDF)
🎵 Listen

Trichord 015 over Rhythm Changes (I Got Rhythm). The available tones for each chord determine which 015 pair positions appear — watch how the pair shifts as the harmony moves through the A and B sections.

015 — SpiderWeb

▶ Score (PDF)
🎵 Listen

Trichord 015 over the changes to Back Home in Indiana. A contrafact built entirely from 015 pair positions — the trichord pair is the sole pitch source throughout.

Trichord 015 over Rhythm Changes with a bass groove feel. Three compositions using the same trichord over the same progressions — each one demonstrates a different approach to deploying the pair.

Example Files

Each file type in the Sonic Twins library is shown below with a representative example. The complete library contains files for all 328 trichord pairs across all twelve keys — these examples show the format and sound of each type.

Chord Voicings — Symmetric 015+015: C Db F / Eb E Ab

Hexachord: C Db Eb E F Ab | Works over: dom7, 7sus4

▶ Score (PDF)
🎵 Listen (MP3)

Six closed-position voicings of the trichord pair cycle through ascending and descending inversions across all twelve keys. Learn the shapes first, then transpose. The goal is automatic recognition of each voicing by ear and by touch.

Trichord Pair Arpeggios — Symmetric 015+015: C Db F / Eb E Ab

Same 6 inversions as chord voicings — arpeggiated in 6/8, all 12 keys

▶ Score (PDF)
🎵 Listen (MP3)

The same six inversions as the chord voicings, presented as flowing 6/8 melodic lines. The shapes are identical — but your ear now hears them as melody rather than harmony. This is the bridge between chordal and linear use of the pair.

Hexachord Scale Run — Asymmetric 026+037: C D Gb / E G B

Hexachord: C D E Gb G B | 2 octaves up + down, all 12 keys

▶ Score (PDF)
🎵 Listen (MP3)

The six-note hexachord as a two-octave ascending and descending scale, starting from middle C. Each key occupies one line. Final note is a dotted half. This is the most direct way to hear the hexachord as a single pitch collection before breaking it into its component trichords.

Vamp Accompaniment — Asymmetric 026+048: C D Gb / Eb G B

Drums + bass + chords | 12 bars loopable | Key of C

🎵 Listen (MP3)

A loopable drum, bass, and chord track — the backing groove for practicing the étude material. Twelve bars, six ascending inversions and six descending, loops cleanly. Use this as your practice backing track while working through the étude files.

Étude Melody — Symmetric 036+036: C Eb Gb / E G Bb

Hexachord: C Eb E Gb G Bb | Works over: dom7, dim7 | Key of C

▶ Score (PDF)
⇓ MIDI
🎵 Melody Only (MP3)
🎻 With Band (MP3)

A 32-bar trombone melody using the trichord pair as its pitch source — quarters, eighths, and eighth triplets. The melody alternates freely between the two trichords. Available as melody only, or merged with the vamp accompaniment for full band context.

Étude With Rests — Asymmetric 027+027: C D G / Db Gb Ab

30% quarter rests on beats | Key of C

▶ Score (PDF)
🎵 Listen (MP3)

The same 32-bar melody with approximately 30% of the quarter-note beats replaced by quarter rests. The rests create phrasing and breathing room. Use this version after the standard étude feels automatic — the rests reveal whether you are truly hearing the material or just executing it mechanically.

Étude Melody — Asymmetric 015+027: C Db F / E A B

Hexachord: C Db E F A B | Key of C

▶ Score (PDF)
⇓ MIDI
🎵 Melody Only (MP3)
🎻 With Band (MP3)

An asymmetric pair combining trichords 015 (C Db F) and 027 (E A B). The hexachord C Db E F A B has a wide interval range — both a half step (C–Db) and a major seventh (Db–C at the octave) — giving the melody a dramatic, wide-ranging character.

Dyad Sequencing — Symmetric 037+037: C Eb G / D F A

Works over: min7 | Dyad pair: C-Eb / D-F | All 12 keys

▶ Score (PDF)

Frequently Asked Questions

Do I need to complete all of Sonic SingleSonic Single before starting Sonic Twins?

You need a solid foundation — comfortable with several trichords across multiple chord types in all twelve keys. You do not need to have completed all twelve trichords. The minimum is a genuine ear-level fluency with the trichords you plan to work with in pairs.

How many trichord pairs does Sonic Twins cover?

328 pairs in total — 69 symmetric and 259 asymmetric. Each pair has files for all twelve keys across all applicable chord types.

What is the difference between symmetric and asymmetric pairs?

A symmetric pair uses two transpositions of the same trichord prime form whose combined hexachord is inversionally symmetric. An asymmetric pair combines two different trichord prime forms. Both are fully covered in Sonic Twins.

What instrument is this written for?

The book and étude files are instrument-agnostic. The étude melodies are notated in treble clef for trombone range but can be played on any pitched instrument. The chord voicings are most directly useful for pianists and guitarists. All MIDI files work with any DAW or MIDI player.

How does Sonic Twins relate to the Sound Cells series?

The Sound Cells series covers all 78 possible trichord pair combinations in individual volumes with compositions and recordings. Sonic Twins is the comprehensive systematic course — étude files, position references, and reference tables for all 328 pairs across all chord types and keys.

What Is a Trichord?

A trichord is any combination of three notes considered as a pitch-class set — defined by the intervals between the notes rather than by the specific pitches used. There are twelve trichord types, called prime forms, that cover all possible three-note interval structures. Every three-note group you have ever played belongs to one of these twelve families.

In standard pitch-class set theory, each prime form is labeled by its interval content in integer notation. The twelve trichords are:

Prime Form	Notes from C	Interval Structure	Common Name
012	C Db D	half step + half step	Chromatic cluster
013	C Db Eb	half step + whole step	—
014	C Db E	half step + minor third	—
015	C Db F	half step + major third	—
016	C Db Gb	half step + tritone	—
024	C D E	whole step + whole step	Whole-tone fragment
025	C D F	whole step + minor third	—
026	C D Gb	whole step + tritone	—
027	C D G	whole step + perfect fifth	Sus2 fragment
036	C Eb Gb	minor third + minor third	Diminished trichord
037	C Eb G	minor third + major third	Minor triad
048	C E Ab	major third + major third	Augmented triad

Each trichord has two structures: Structure 1 (S1) is the prime form as shown; Structure 2 (S2) is its inversion — the same interval content read bottom to top in reverse. For trichords where S1 and S2 produce the same interval content (like 036 and 048), there is effectively one structure. For all others, S1 and S2 are distinct and both are covered in the étude files.

The Sonic Single System

Sonic Single is built on one question: for a given trichord, which positions of that trichord are available over a given chord type, and how do you develop the speed and ear to use them at performance tempo?

The answer requires three things: knowing which positions are available (the reference material), hearing what they sound like against the chord (the listening practice), and training the fingers to execute them automatically (the étude practice). Sonic Single provides all three for every trichord over every chord type in every key.

Eight Chord Types

The available positions for each trichord are determined by which notes of the trichord qualify as available tones over the chord — chord tones and recognized tensions that sound consonant rather than wrong. Sonic Single covers eight chord types:

Chord Type	Symbol	Available Degrees
Major 7	Δ7	1, 2, 3, #11, 5, 6, 7
Minor 7	-7	1, 2, b3, 4, 5, 6, b7
Dominant 7	7	1, b2, 2, b3, 3, #11, 5, b6, 6, b7
7sus4	7sus4	1, b2, 2, b3, 3, 4, 5, b6, 6, b7
Minor/Major 7	-Δ7	1, 2, b3, 4, #11, 5, 6, 7
Minor 7b5	-7b5	1, 2, b3, 4, b5, b6, b7
Diminished 7	°7	1, 2, b3, 4, b5, b6, bb7, 7
Major 7#5	Δ7#5	1, 2, 3, #11, 5, #5, 7

34 Progressions

The étude files cover 34 chord progressions drawn from the most common harmonic sequences in jazz and modern music — ii-V-I, blues, Rhythm Changes, modal vamps, and more. Each progression is notated at the top of the score with Roman numeral analysis and chord symbols. The progressions increase in complexity, from single-chord vamps (progressions 1–8) through two-chord alternations and finally through multi-chord sequences that require the ear to track position changes across the bar line.

Trichords in Practice: Compositions

The fastest way to hear a trichord is to listen to music built from it. The compositions below were written using specific trichords as their primary pitch source. Follow the score while you listen — notice how the same three-note shapes appear in different inversions and transpositions throughout the piece. This is the sound you are working toward in the étude practice.

012 — Chromatic Reasoning

▶ Score (PDF)
🎵 Listen

Trichord 012 is the most chromatic of all twelve prime forms — three consecutive half steps. Over the available tones of a dominant 7 or 7sus4 it finds six positions; over most other chord types it has none. Chromatic Reasoning shows what a composition built entirely from this concentrated, half-step-saturated structure sounds like over a moving progression.

013 — 013 Blues in B

▶ Score (PDF)
🎵 Listen

Trichord 013 is one of the most versatile in the system — it works over all eight chord types. 013 Blues in B places both structures over a blues progression. Art of the Blues contains twelve versions of a blues progression using the 013 trichord with different approaches on each.

014 — Numbers

▶ Score (PDF)
🎵 Listen

Trichord 014 spans a half step and a major third — an interval combination that sits slightly outside familiar triadic shapes while remaining firmly inside the available tones of the chord. Numbers uses both structures of 014 over a standard jazz progression.

015 — Entanglement, SpiderWeb, and Tangible

Entanglement:
▶ Score (PDF)
🎵 Listen

SpiderWeb:
▶ Score (PDF)
🎵 Listen

Tangible:
▶ Score (PDF)
🎵 Listen

Three compositions using trichord 015 are included because 015 is the central example throughout this book. Entanglement and Tangible use Rhythm Changes; SpiderWeb uses the changes to “Back Home in Indiana.” In all three, available chord tones and tensions determine which 015 positions appear.

016 — Smoke

▶ Score (PDF)
🎵 Listen

Trichord 016 contains a tritone — a half step and a tritone in either order. This gives it an edgy, suspended quality that sits particularly well over dominant 7 chords, where it yields eight valid positions. Smoke makes full use of that range.

024 — Grey and Brown

▶ Score (PDF)
🎵 Listen

Trichord 024 is built from two whole steps — the most symmetric of the non-symmetric-feeling trichords, immediately connected to pentatonic and major scale sounds. Grey and Brown isolates that sound and makes it the entire language of the piece.

025 — Beauty Queen

▶ Score (PDF)
🎵 Listen

Trichord 025 spans a whole step and a perfect fourth — a combination that gives it a spacious, open quality. It works over all eight chord types. Beauty Queen shows 025 in a context where that openness is foregrounded.

026 — Derivative

▶ Score (PDF)
🎵 Listen

Trichord 026 combines a whole step and a tritone. Like 016 it yields eight positions over the dominant 7 chord. Derivative works through both structures across a progression that highlights the different colors each structure brings.

027 — A Day in the Badlands

▶ Score (PDF)
🎵 Listen

Trichord 027 — a whole step and a perfect fifth — is the most naturally resonant of all twelve trichords. It appears in every diatonic scale family and both pentatonic scales. A Day in the Badlands shows what that accessibility sounds like when developed into a complete musical statement.

Example Files

Each file below is a representative example of one of the four étude types included with Sonic Single. The score shows the first page of the notation; the audio plays a rendered version of the file. The full library contains 34 progressions per trichord across all twelve keys — these examples show the format so you know what to expect when you open the files.

Melodic Étude — Trichord 013, Progression 28

E-7 Eb°7 D-7 G7 (III-7 bIII°7 II-7 V7)

▶ Score (PDF)
🎵 Listen (MP3)
⇓ MIDI

The melodic étude is the foundation of Sonic Single practice. Constant eighth notes cycle through all valid positions of the trichord over the chord progression, transposed through all twelve keys. Structure S1 appears first, then S2. The goal is even, automatic execution — drilling the trichord positions into muscle memory and ear simultaneously.

This example uses trichord 013 over a minor turnaround (III-7 bIII°7 II-7 V7), Progression 28. The two structures of 013 — a half step plus a minor third (S1) and a minor third plus a half step (S2) — appear in all their valid positions over the minor 7, diminished 7, minor 7, and dominant 7 chords. The audio plays the first key; the full file covers all twelve.

Chord Étude — Trichord 027, Progression 16

C-7 EbΔ7 AbΔ7 G7 (I-7 bIIIΔ7 bVIΔ7 V7)

▶ Score (PDF)
🎵 Listen (MP3)
⇓ MIDI

The chord étude presents each trichord position as a voiced three-note chord rather than a melodic line — for pianists, guitarists, and anyone working with harmony. The rhythm is a characteristic jazz comping figure. This example uses trichord 027 — a whole step and a perfect fifth — over a minor progression with major 7 substitutions. The open, resonant quality of 027 is especially effective in a chordal context.

Étude With Rests — Trichord 037, Progression 10

CΔ7 Eb7 Ab7 Db7 (IΔ7 bII7 bVI7 bII7)

▶ Score (PDF)
🎵 Listen (MP3)
⇓ MIDI

The étude with rests uses the same trichord positions as the melodic étude but breaks up the constant eighth-note stream with rests. This creates more conversational phrasing — and reveals whether you have truly internalized the material. If the rests feel like interruptions you are fighting against, the underlying étude needs more practice. This example uses trichord 037 (the minor triad) over a descending whole-step progression.

Individual Positions — Trichord 025, Structure S1

All valid positions of 025 S1 over each chord type — keys of C and F shown

▶ Score (PDF)
🎵 Listen (MP3)
⇓ MIDI

The positions file is a reference document as much as a practice file. Rather than running the trichord over a progression, it isolates each valid position of one structure over one chord type at a time, in all twelve keys. This gives you a direct view of the available tones — exactly which notes of the trichord align with which scale degrees over each chord. Where a chord type shows no positions, the trichord has no available placement over that chord.

Sonic Twins Preview Examples

The following two examples are from Sonic Twins — the companion course to Sonic Single. Where Sonic Single works with one trichord at a time, Sonic Twins works with pairs: two trichords that share a symmetric or asymmetric relationship, used together over a chord progression.

Sonic Twins — Trichord 026, Symmetric Pairs, Structure S2

026 [0,4,6] — all valid symmetric pairs over each chord type

▶ Score (PDF)
🎵 Listen (MP3)
⇓ MIDI

A symmetric pair is two transpositions of the same trichord that together produce a symmetrical pitch-class set. For trichord 026 S2 — a major third plus a whole step — the symmetric pairs are transpositions where the two 026 trichords share a tritone relationship. The file works through all valid symmetric pairs of 026 S2 over each chord type, in all twelve keys.

Sonic Twins — Trichord 037, Asymmetric Pairs

037 [0,3,7] — all valid asymmetric pairs over each chord type

▶ Score (PDF)
🎵 Listen (MP3)
⇓ MIDI

An asymmetric pair uses two different transpositions of the trichord that do not form a symmetrical set. For trichord 037 — the minor triad — the asymmetric pairs produce a wider range of harmonic colors. 037 is one of the most harmonically active trichords in the Sonic Twins system because the minor triad appears in so many chord types and scale families.

Recommended Practice Path

Listen first. Before playing a file, listen to the audio version while following the score. Let the ear hear the pattern before the hands play it.
Sing it. Use solfeggio syllables and sing the melody against a drone before touching your instrument.
Play slowly. Work through the first key at a tempo where every note is deliberate and in tune. Speed comes from accuracy, not from pushing tempo.
Transpose in circle-of-fourths order. C, F, Bb, Eb, Ab, Db, Gb, B, E, A, D, G — each new key is a fourth away from the last. This is the most musically natural transposition order.
Use a drone. Every étude is designed to be practiced against a drone on the key center. Without a drone you are training fingers without training ears.
One trichord at a time. Complete one trichord across all 34 progressions before moving to the next. The system is cumulative — the later trichords will make more sense once the earlier ones are in your ear.

Ear Training Path

Everything in this book depends on one ability: hearing pitches in relationship to a key center. This is a trained skill, not a natural one. Three levels of training are recommended, practiced concurrently:

Level	Resource	What It Builds
1	Ear Training One Note Complete	Identify any of the twelve chromatic pitches against a key center — by ear, not by counting intervals.
2	Contextual Ear Training	Hear pitches in context of real chord progressions — how harmonic function changes what a note sounds like.
3 — Critical	SerialEar	Hear all twelve trichords — every inversion, every transposition — against a drone. This is what makes the étude material audible rather than mechanical.

Frequently Asked Questions

Do I need to know music theory to use this book?

You need to be able to read standard music notation and understand basic chord symbols (Maj7, -7, 7, etc.). The book explains pitch-class set theory from scratch in the introduction, so no prior knowledge of that is required. A working understanding of chord tones and tensions for the eight chord types covered is helpful; Chapter 5 of the book documents all of them.

How long does it take to complete the system?

This is entirely dependent on how much you practice and at what depth. Some students spend a year on a single trichord, going deep on all 34 progressions in all twelve keys. Others move faster through more material at shallower depth. The honest answer is that the system is large enough to support years of serious practice — and the ear training that makes the material meaningful takes as long as it takes.

What instrument is this written for?

The book is instrument-agnostic. All études are notated in treble clef in standard notation. The chord étude files are most directly useful for pianists and guitarists, but any pitched instrument can use all the files. The MIDI files work with any DAW or MIDI playback setup.

Is this related to Sonic Twins?

Yes. Sonic Single is the prerequisite to Sonic Twins. Complete Sonic Single — or at least develop a solid foundation with several trichords across multiple progressions — before starting Sonic Twins. The Sonic Twins examples in Chapter 4 of this book give you a preview of where the system goes.

Do the MIDI files require a specific software setup?

Any MIDI player or DAW will open the files. The files are standard General MIDI, so any soundfont or software instrument will play them back. For the best results, use a high-quality piano or instrument sound that responds to velocity, so the musical phrasing of the étude is clear.

A Three-Century Pedagogical Lineage

The principle of hearing music from a tonal center was passed forward through three centuries of teaching. The core chain runs: Scarlatti → Porpora → Haydn → Beethoven → Czerny → Vengerova → Madame Chaloff → Banacos → Bruce Arnold.

Bruce Arnold studied with Charlie Banacos and Jerry Bergonzi. That training — the insistence on hearing every note in relationship to a single key center — is the foundation on which the entire Sonic Single system is built.

Alessandro Scarlatti (1660–1725)
Nicola Porpora (1686–1768)
Joseph Haydn (1732–1809)
Ludwig van Beethoven (1770–1827)
Carl Czerny (1791–1857)
Isabelle Vengerova (1877–1956)
Madame Chaloff (1900–1977)

Symmetrical Harmony, Subsets, and Modular Scale Applications for Modern Improvisation

By Bruce Arnold — Muse Eek Publishing Inc. — ISBN 978-1-59489-178-6

A discovery with no precedent in the chord-scale literature.

Of all possible seven-note scales, exactly one has all twelve of its chromatic transpositions functioning over real chords in real chord progressions. That scale is Melodic Minor Ascending — and this book is the complete system built on that finding.

Why Learn MMA? The Argument Most Students Never Hear

Most students who encounter Melodic Minor Ascending hit the same wall. They look at the seven diatonic chords of the scale and see three chord qualities that don’t show up in their everyday playing:

MMA Mode	Chord Quality	Common reaction
Mode I — MMA itself	C-Δ7 (minor-major 7)	“I use this sometimes”
Mode II — Dorian ♭2	D7sus4♭9	“I almost never see this”
Mode III — Lydian ♯5	E♭Δ7♯5	“When would I use this?”
Mode IV — Lydian Dominant	F7♯11	“Yes, this I know”
Mode V — Mixolydian ♭13	G7♭13	“Yes, this too”
Mode VI — Locrian ♮2	A-7♭5add9	“Half-diminished add 9? Skip.”
Mode VII — Altered	B7alt	“This I definitely need”

The conclusion most students reach: “I only need Lydian Dominant, Mixolydian ♭13, and the Altered scale. I can skip the rest — and maybe skip MMA altogether.”

This is the single most common reason students abandon MMA before it has a chance to work. And it is based on a fundamental misreading of what the system is showing.

The misunderstanding: those “rare” chord qualities aren’t home chords. They’re keys to secondary dominants.

When you learn the MMA transposition rooted on E♭ — whose home chord is E♭Δ7♯5 — you are not learning a scale for E♭Δ7♯5 chords specifically. You are learning a transposition whose seven diatonic chords include a Lydian Dominant, an Altered dominant, a Mixolydian ♭13, and a half-diminished — all the sounds you already use, now available from one new key center.

Secondary Dominants: Where This System Actually Lives

Secondary dominants — dominant-function chords borrowed to tonicize scale degrees other than the tonic — appear in roughly 90% of Western tonal music. Jazz standards, blues, pop, country, classical harmony: the secondary dominant is everywhere. In any key, there are twelve dominant-function chords: the V7 of the key, plus the secondary dominant of every other scale degree.

Before knowing about the SuperScale property, the practical case for MMA was already strong: all seven MMA modes function over secondary dominants. That includes Dorian ♭2, Lydian ♯5, and Locrian ♮2 — the three modes students assume are too rare to bother with. Every one of those transpositions is the scale you need over a secondary dominant that appears constantly in real repertoire.

A concrete example: In the key of C, the chord E7 is V/vi — the secondary dominant of A minor. The correct MMA transposition is B MMA (starting from the fifth of E). That transposition’s home chord is B-Δ7 — another “rare” chord quality. But B MMA over E7 gives you the Altered sound, one of the most useful colors in jazz. You weren’t learning a scale for B-Δ7 chords. You were learning what to play over E7 — a chord that shows up in hundreds of standard tunes.

The SuperScale discovery takes this further: not just “all seven modes are useful” but “all twelve chromatic transpositions cover all twelve dominant-function chords in a single key center, verified computationally.” That is the deeper reason to learn every MMA transposition — including the ones whose home chord you think you’ll never encounter. You’re not learning it for the home chord. You’re learning it for the six other chords inside that transposition, several of which you use every time you play a standard.

If you skip this transposition…	You lose access to these secondary dominants in C
E♭ MMA (home: E♭Δ7♯5)	A♭7♯11, B♭7♭13, C-7♭5, D7alt — all common in jazz standards
D MMA (home: D-Δ7)	G7♯11, A7♭13, B-7♭5, D♭7alt — V7 of G, V7 of A, and more
A♭ MMA (home: A♭-Δ7)	D♭7♯11, E♭7♭13, F-7♭5, G7alt — tritone subs and secondary dominants throughout

This is why the book covers all twelve transpositions, and why the practice materials are organized to build fluency in each one from a single key center. Skipping the “unfamiliar” home chords means skipping the secondary dominant vocabulary that appears in almost every song you will ever play.

What Is a SuperScale?

Music theory classifies scales by their internal interval structure — the pattern of whole steps and half steps that gives a scale its characteristic sound. This book is concerned with a different property entirely: not how a scale sounds in isolation, but how its twelve chromatic transpositions relate to the harmonic world around them.

A SuperScale is a pitch-class collection meeting two conditions simultaneously:

All twelve of its chromatic transpositions must each form a recognized, musically usable scale.
Each of those twelve transpositions must function over a real chord in an actual chord progression — confirmed computationally, not assumed theoretically.

Both conditions must be met. The bar is high. That is precisely why the catalog of SuperScales is small — and why the seven-note result is so striking.

Why this matters for improvisation: Jazz harmony, as most commonly taught, is organized chord by chord. Each chord generates its own scale universe. The improviser follows the changes, switching scale thinking with each new chord symbol. The SuperScale property offers an alternative: a single scale family that covers all twelve dominant-function chords in a key — reducing cognitive load and keeping the ear anchored while the harmony moves underneath.

The Melodic Minor Ascending System

Of all possible seven-note scales, exactly one — Melodic Minor Ascending (set class 7-34, interval pattern W-H-W-W-W-W-H) — passes both SuperScale conditions for all twelve transpositions. Every other seven-note scale fails at least one condition for at least one transposition.

In the key of C, all twelve dominant-function chords — the tonic dominant plus all eleven secondary dominants — map precisely onto the twelve chromatic transpositions of MMA. The book includes the complete reference table for this mapping, with every chord, its corresponding MMA transposition, and its relationship to the key center. It is the core reference of the entire system, and it is immediately playable: every entry is a real chord from real repertoire paired with the MMA transposition that serves it.

There is a simple interval relationship that locates the correct transposition for any dominant chord, and it is explained in full in Chapter 2. But as the book makes clear, knowing the relationship and hearing the relationship are two different things — and only one of them works at performance tempo.

12 transpositions × 7 diatonic chords each = 84 distinct chord–scale relationships covered by one scale family, from one key center, without switching harmonic frameworks. That is before counting the subset scales within each transposition or the trichord pair applications.

The Banacos connection: Charlie Banacos taught that you should hear as much as possible from one tonal center — reduce cognitive load, let the ear stay anchored while the harmony moves. The MMA discovery is a Banacos question: it could only have been asked by someone trained to hear that way. His influence runs through every chapter of this book.

The MMA Subsets — Three Tools, Three Sounds

The full seven-note MMA scale is the Rosetta Stone of the system. But the subsets drawn from it — the 4-, 5-, and 6-note collections that live inside MMA — are where many players will spend most of their time. Each size has a distinct musical character and a distinct set of applications. They are not simplified versions of the full system. They are different tools.

6-Note Subsets — Hexatonics
10 confirmed SuperScales • Chapter 5

The six-note subsets of MMA are the sound of modern jazz harmony. Six notes leave six chromatic pitches unplayed — enough open space to avoid sounding scale-like, enough density to imply clear harmonic color. This is the sweet spot for sophisticated jazz improvisation: the hexatonics give you a contemporary, intervallic sound that sits comfortably over dominant and altered dominant chords without telegraphing every note of the underlying scale.

If you have worked through any of the Sound Cells series, you already know the hexatonic world. The MMA hexatonics are the subset of that world that maps directly onto the MMA key-center system — the same interval structures, now organized by transposition and confirmed computationally to function over real harmonic situations.

Best for: Jazz improvisation • Modern harmony • Post-bop and contemporary styles • Players already familiar with hexatonic superimposition who want a systematic key-center framework

5-Note Subsets — Pentatonics
12 confirmed SuperScales • Chapter 5

Pentatonics are universal. Every player knows the minor pentatonic. Most know the major pentatonic. The MMA system gives you 21 five-note subsets — all the pentatonic scales that live inside Melodic Minor Ascending, organized by key center and confirmed to function over real chords.

For rock and metal players especially, this is the most immediately actionable part of the book. You already think in pentatonics. The MMA pentatonic subsets hand you a systematic way to move beyond the minor and major boxes into sounds that are fresh without being foreign — still pentatonic in feel, but with interval structures you have not heard from your fingers before. Over a static dominant chord or a drone, these are immediately striking. They do not require a jazz context to work.

The full reference for all 38 pentatonic prime forms and their modes is documented in the Sonic Resource Guide (available separately). The MMA pentatonic subsets are the subset of that catalog confirmed to function within the MMA key-center system.

Best for: Rock and metal players • Any style where pentatonics are already the primary vocabulary • Players who want fresh sounds without abandoning the pentatonic feel • Immediate application over drones and static harmony

4-Note Subsets — Arpeggios & Chords
16 confirmed SuperScales • Highest richness in the catalog • Chapter 5

Four notes leave eight chromatic pitches unplayed. That open space is not emptiness — it is harmonic freedom. The four-note subsets have the highest average richness values in the entire SuperScale catalog, meaning they fit over the widest range of chords with the fewest conflicts. They are the most harmonically flexible material in the system.

In practice, four-note collections are the natural language of arpeggios and chord voicings. Every four-note subset in Chapter 5 is directly applicable as an arpeggio pattern — a complete melodic gesture that implies harmony without spelling it out note by note. For chord-melody players, composers, and anyone working with voicing-based improvisation, the four-note subsets give you a systematic library of arpeggio shapes drawn from the MMA system, each confirmed to function over real chord changes.

They are also the easiest entry point into the system. Fewer notes means less to track mentally, and the high richness means even a beginner with the MMA system will hear these land correctly over the MIDI drone files from the first practice session.

Best for: Arpeggio-based playing • Chord voicing and chord-melody • Composers working with intervallic harmony • Beginning the MMA system • Highest harmonic richness of any subset size

The complete SuperScale catalog by size — trichords through octatonics, with richness values and prime forms for every confirmed SuperScale — is documented in Appendix B of the book.

Recommended Practice Path

Read Chapters 8–10 before beginning the exercises. They give you the mental, physical, and rhythmic tools that make every exercise more efficient and less likely to result in injury or wasted repetition.

MMA Chord Charts in C — Begin with the twelve MMA transpositions in the key of C. Work slowly, singing each scale against the drone in the MIDI file. One transposition at a time, until the sound is in your ear before moving to the next key.
4-Note Subsets — Move to the subset exercises only after the full MMA transpositions feel secure. Start with four-note subsets, which offer the highest harmonic density. The five- and six-note subsets build on that foundation.
Trichord Pair Études — The advanced layer. Work these only after the chord charts and subset exercises feel solid. Start with pairs that use familiar trichord types — 027 pairs are a natural entry point — and build toward less common prime form combinations.
Modal Sequencing — Use the modal sequencing files to develop fluency in hearing each transposition as a continuous melodic gesture across all twelve keys.

The most common mistake: practicing without a drone. Every exercise in this book is designed to be practiced against a drone. Without one, you are training your fingers without training your ear. The MIDI drones are included in every download package for exactly this reason.

Ear Training Path

Everything in this book depends on one ability: hearing pitches in relationship to a key center rather than as isolated notes or intervals. This is a trained skill, not a natural one. The recommended path is sequential — each level makes the next possible — but all three levels should be practiced concurrently once begun.

Level	Resource	What It Builds
1	Ear Training One Note Complete	Hear a single pitch against a key center and identify which of the twelve chromatic degrees it is — not by counting intervals but by recognizing the specific sound of that degree.
2	Contextual Ear Training	Hear pitches in the context of real chord progressions — understanding not just what a note is, but how it functions given what is happening harmonically around it.
3 — Critical	SerialEar	Hear all possible three-note structures (every trichord, every inversion, every transposition) against a drone in a key-center context. This is the step that makes the twelve MMA transpositions audible as twelve different colorings of one key center rather than twelve separate things to memorize.

Not yet sure where to start? The free Ear Training Guided Tour explains the difference between interval-based and key-center hearing and maps the full curriculum.

Recommended Companion Volumes

Book	How It Relates
Scale Analysis ISBN 978-1-59489-431-2	The practical companion to SuperScales. Applies the key-center approach to real chord progressions — twelve-bar blues, minor blues, and Rhythm Changes — across all 12 keys. Covers 28 prime forms including all seven MMA modes. If SuperScales is “why it works,” Scale Analysis is “how to hear it.”
My Music ISBN 1-890944-11-4	The theoretical and historical foundation for the MMA Trichord Pairs system in Chapter 6. Traces the compositional lineage from Stravinsky and Banacos through McCoy Tyner, and presents the harmonic rhythm principle — pivoting between two trichords in groups of 2, 3, or 4 eighth notes — that underlies the pivot exercises in the download package.
Sound Cells, Vols. 1–78 (forthcoming)	Covers all 78 possible trichord pair combinations, one per volume. Students who want to extend the trichord pair work in Chapter 6 beyond MMA — applying it to other hexatonic collections and harmonic contexts — will find the Sound Cells series the natural next step.
SuperScales II (forthcoming)	Takes the 84 diatonic chords across the 12 MMA transpositions as harmonic destinations in their own right. The compositional language of Wayne Shorter, Herbie Hancock, Bartók, and the broader post-functional harmony tradition — built on the aural foundation developed in this book.
SuperScales III (forthcoming)	Covers the eight-note SuperScale catalog in full — a complete practice framework parallel to the one in this volume, centered on the octatonic candidate C, D♭, E♭, E, G♭, G, A, B♭.

Frequently Asked Questions

Do I need to know all 12 MMA transpositions before the system is useful?

No. The system is modular. Begin with the key of C, work through each transposition until the sound is in your ear, then move to one adjacent key. Even a partial command of the system — two or three keys — expands the harmonic vocabulary available from a single tonal center.

Is there a formula for finding the right MMA transposition over a dominant chord?

Yes, there are a few ways to formulate a reference to the correct MMA transposition, and they are shown in the book. But understand what this is: a crutch. At performance tempo, any calculation disappears. The goal is direct recognition — you know where you are in the key, you know the degree, and you hear the MMA sound that belongs there. The formula tells you where to go. Ear training is what makes you stop needing directions.

Can I use this system over non-dominant chords?

This volume concentrates on the twelve-transposition property specifically for dominant-function chords. There are also sections where each MMA transposition’s seven diatonic chords are covered — several of which are non-dominant qualities (minor-major 7, major 7 sharp 5, half-diminished add 9) — as part of each transposition’s harmonic universe. Overall the book concentrates on the use of the 12 dominant chords via the transpositions of the MMA scale. The subset exercises in Chapter 5 further extend the system’s reach into non-dominant territory.

Does the system require abandoning chord-by-chord scale thinking?

No — it offers an alternative, not a replacement. The chord-by-chord approach is powerful and widely used. The MMA system works best where music gives it room: on dominant chords held long enough to be heard, or on fast-moving changes where the ear stays in one key naturally. Learning to sense when the ear is staying and when it is moving is itself a musical skill that develops through the same practice as everything else in this book.

What instrument is this book written for?

The book is pitch-based and instrument-agnostic. The chord charts and subset exercises are written in treble clef in standard notation and apply equally to any pitched instrument. The MIDI practice files work with any DAW or MIDI playback setup. The trichord pair études are notated in standard treble clef notation. There are no bass clef notation examples in this book.

A Three-Century Pedagogical Lineage

The principle of hearing music from a tonal center was not invented by Charlie Banacos. It was passed forward through three centuries of teaching. The core chain runs: Scarlatti → Porpora → Haydn → Beethoven → Czerny → Vengerova → Madame Chaloff → Banacos → Bruce Arnold.

Bruce Arnold studied with Banacos for five years. That training made the MMA discovery musically meaningful rather than merely mathematical. By working through the material in this book, you join that lineage.

Alessandro Scarlatti (1660–1725)
Nicola Porpora (1686–1768)
Joseph Haydn (1732–1809)
Ludwig van Beethoven (1770–1827)
Carl Czerny (1791–1857)

Trichord Pairs — A Scientific Approach to
Melodic and Harmonic Mastery

This course covers a specific group of trichord pairs (also known as triad pairs) that
get used often when improvising. They are very useful as chords and melodic
replacements for the modes of major and melodic minor ascending. This course lists all
the possible 027-016 and 027-026 trichord pair combinations. What that means is you
have easy-to-play structures that will sound super modern but are also very harmonious
in any musical situation. These aren’t abstract strange sounds — they are core
structures used when playing a jazz standard or even rock, metal, and blues.

You also don’t need knowledge of pitch class sets or other special music theory
constructs. You just have a very useful sound laid out for you either as a scale, two triad
pairs, or awesome sequences that give you head-turning attention when you play them!
But if you do want to dig deeper there is an Appendix that covers in-depth the music
theory concepts found in this book. That material is from the Sonic Resource
Guide, a go-to reference used often.

Why a whole step and fifth (027) matched against either a half step and a tritone
(016) or a whole step and tritone (026)? The 027 is often used as a fourth voicing, and
melodies moving in fourths or dominant chords are often voiced with an 016 or 026 in
the upper three notes. So these combinations play sounds that aren’t going to upset
more conservative musicians, but moving between them creates a pretty unique sound
that tends to land well with most listeners. These combinations are also not difficult to
play, voice-lead well, and are easier to get into your playing fast — as opposed to
012, 013, 014, and similar sets, which are awesome sounds but take a while to get used
to.

For as long as musicians have had scales, most reach for the same handful of them
over every mode of major and melodic minor — and the same handful of chords
underneath. Trichord Pairs identifies something more specific: the exact
combinations of a 027 trichord matched against a 026 or 016 trichord that sound
genuinely striking as replacements for that default vocabulary, worked out
independently for every mode of both scales, in every key.

Naming the harmony is the easy part. This book pairs that system
with the mental practice method, physical technique, and rhythmic tool you need to
actually get it into your ear and your hands — without the repetitive-strain grind
that ends so many promising technical projects.

What This System Gives You:

Every Valid Combination, Both Scales: All 28 valid 027-016
combinations across the seven modes of major, and all 42 valid 027-026 combinations
across the seven modes of melodic minor ascending — each independently
verified, not just relabeled from mode to mode.
A Synopsis of the Mental Practice Method:
Build a stable virtual instrument, fire the same motor pathways as live performance
below the threshold of movement, and use the ten minutes before sleep to hardwire a
combination into permanent memory.
Long Line Rhythm Applied Directly: The macro-pulse, anchor-point method that keeps an eighteen-bar sequence or
a two-octave scale run from turning into a note-by-note grind. Read about the MetroDrone and Long Line Rhythm for more
information.
Technique That Won’t Cost You Your Hands: The Home

Trichord Pairs 2 — Harmonic Minor,
Harmonic Major, and the Symmetric Scales

Trichord Pairs covered major and melodic minor ascending —
the two scales where the 027-016 and 027-026 pairing system produces the richest set
of combinations, four to six per mode. Trichord Pairs 2 takes the same
method into different territory: harmonic minor, harmonic major, and the three symmetric
scales, where the underlying interval structure changes the math entirely.

Harmonic minor and harmonic major both contain an augmented second —
and that interval narrows the valid 027-026 pairing down to exactly one combination per
mode, rather than several. This book includes both of harmonic minor’s most commonly
used modes (the tonic harmonic minor sound, and the fifth mode’s Phrygian Dominant
— the classic altered-V7 sound), and all seven modes of harmonic major.

The symmetric scales — Whole-Half Diminished, Half-Whole Diminished,
and Whole Tone — work differently again. These scales repeat their own interval
pattern around the octave, so there’s no single 027 trichord anchoring every
combination the way there is in major or melodic minor. Instead, every combination in
this section pairs two 026 trichords against each other, and because the diminished
scales are eight notes rather than seven or six, there’s substantially more valid
combinations to work through — sixteen each for the two diminished scales, six
for whole tone, where every note of the scale is used with nothing left over.

Beyond the reference charts, this edition adds two new practice formats built for
taking a single trichord to the instrument. Sweeps takes each individual
trichord in the book through its three inversions, each swept up two octaves and back
down in a register built specifically to be playable on guitar. Pair Sweeps
links a combination’s two trichords into one continuous gesture — one trichord
sweeping up, the other sweeping back down — cycling through all three
inversions of both.

The complete mental practice, technique, and Long Line Rhythm system from
Trichord Pairs carries over unchanged — this book assumes you’re
either working through it alongside the original or have been through that material once
already.

What This System Gives You:

Harmonic Minor, Fully Covered: The tonic Harmonic Minor
sound and the Phrygian Dominant (mode 5) — the two modes of harmonic minor
musicians reach for most.
Harmonic Major, All 7 Modes: One verified 027-026
combination per mode — the single valid pairing this scale’s own interval
structure allows.
All Three Symmetric Scales: 16 combinations from WholeHalf Diminished, 16 from Half-Whole Diminished, and 6 from Whole Tone — 38
combinations total from scales most trichord-pair material never touches.
Sweeps and Pair Sweeps: Every individual trichord in the
book taken through its three inversions in a guitar-practical register, plus every
combination linked into a continuous ascending-and-descending Pair Sweep.
The Same Complete Practice System: Mental practice,
Home Base technique, and Long Line Rhythm, applied directly to this new material.
Full PDF and MIDI Practice Files: Five kinds of files
— Overview, Sequence, Scale-Run, Sweep, and Pair Sweep — every
combination voiced eighteen ways and run through all twelve keys.

Trichord Sequencing — The Major Scale and
Melodic Minor, with Six-Sweep and Cascade Sweep

Trichord Sequencing takes the same major and melodic minor material as
Trichord Pairs — all seven modes of each — and adds two
brand-new sequencing formats built specifically around linking a pair’s two trichords
into a single continuous line.

The harmonic groundwork is identical to Trichord Pairs: major keeps its
full seven-mode, twenty-eight combination treatment, and melodic minor keeps its own
full seven-mode treatment too — forty-two combinations, the same complete
dataset as Trichord Pairs, not a narrower root-form-only version.

What’s new here is Six-Sweep and Cascade Sweep
— two ways of linking a combination’s two trichords into one unbroken line. Six-
Sweep draws on all three inversions of both trichords — six sweeps in total
— and links them into a single, continuous, ever-climbing line that alternates
ascending and descending until every inversion of both trichords has been played.
Cascade Sweep takes a different approach: it merges a pair’s two trichords into the six-
note scale their combined pitches form, then walks up that scale a step at a time,
adding the next note of whichever trichord that scale degree belongs to as a second
note at every step.

Seventy combinations in total, all provided across all twelve keys, in four practice
file formats — and the same complete mental practice, technique, and Long Line
Rhythm system as the rest of the series.

What This System Gives You:

The Complete Major Scale System: All 28 valid 027-016
combinations across all seven modes — identical to Trichord Pairs.

The Complete Melodic Minor System: All 42 valid 027-026
combinations across all seven modes — identical to Trichord Pairs, not a
narrower root-form-only treatment.

Six-Sweep: Every combination’s two trichords swept through
all three inversions each, chained into one continuous, ever-climbing line —
found only in this volume.

Cascade Sweep: Every combination’s two trichords woven
together, one note at a time, into a single ascending-and-descending line —
found only in this volume.

The Same Complete Practice System: Mental practice,
Home Base technique, and Long Line Rhythm, unchanged from Trichord Pairs.

Course Prerequisites & Recommendations:
You don’t need good ear training skills for any book in this series, but a foundation in
contextual, key-center-based hearing is highly recommended — Appendix A in
every book lays out the ear-training curriculum this material depends on. For optimum
results, work through the combinations alongside a key-center-producing device like the
MetroDrone® app.

Chapter 3 in every book gives you enough physical technique to
work safely through this material, but it isn’t a complete guitar method — pair it
with Guitar Technique and Physiology for the full treatment, and see The Sonic Resource Guide for the deepest treatment of pitch class set theory.

Frequently Asked Questions

There are a lot of technical exercises in this book. How do I make music out of them?

Trichord Pairs Series has a lot of technical exercises in it and my recommendation is to take each new technical idea and apply it to static chord progressions and then expand into whole chord progressions. I would also highly recommend writing song based on these technical patterns. That way you can see and hear them used in real music and get away from the technique side of things. Getting any new sound into your playing is a task. Be patient with this part of the work. It takes a long time for these ideas to become second nature to you but steady practicing and application to real music will get your there over time.

What’s the difference between the three books?

Trichord Pairs covers all seven modes of major and all
seven modes of melodic minor — the widest coverage of the two richest scales
for this system. Trichord Pairs 2 covers different territory entirely: harmonic
minor, harmonic major, and the three symmetric scales, plus two practice formats built
around a single trichord’s own inversions — Sweeps and Pair Sweeps, which draw
on trichords from across the whole series. Trichord Sequencing takes the
same major and melodic minor material as Trichord Pairs and works it into two
sequencing formats found nowhere else in the series, Six-Sweep and Cascade Sweep,
which link a pair’s two trichords into one continuous line rather than treating them as
separate practice units.

Do I need to buy them in order, or own Trichord Pairs before
the others?

No. Each book stands completely on its own and includes the full
mental practice, technique, and rhythm system in Chapters 2 through 4, so you don’t
need any of the other books to use any one of them. If you already own one and know
that method well, you can move through those chapters quickly in the others.

Is the bundle a one-time purchase or a subscription?

One-time purchase. The bundle unlocks all three digital books, along
with their full PDF and MIDI practice file sets, for immediate download — no
subscription or recurring charge.

What other books do you recommend using alongside this
series?

A few that pair naturally with the material in these books: Mental Practice for Musicians for a deeper treatment of the mental practice method used throughout, Guitar Technique and Physiology for the full hand-position and picking curriculum, The Sonic Resource Guide for the complete pitch class set theory behind each book’s Appendix B, and Ear Training One Note Complete and Contextual Ear Training to build the key-center hearing this whole system depends on.

What should I use to improvise over these combinations?

Get a looper if you can, and build loops using the two trichords as a
scale to solo over. If a looper isn’t an option, Jam Tracks Volume One, available on the Muse
Eek Publishing website, works well for this.

How much should I practice these trichord pairs each day?

As a starting point, spend about 30 minutes playing and memorizing a
single combination through one key. Then spend another 15 minutes improvising with
the scale, and with the chords if you play a chordal instrument. That’s a good baseline
— build up from there as it becomes comfortable.

Do I need to already know pitch class set theory to use these
books?

No. Appendix B in every book is a complete primer — prime
form, integer notation, and chord tones, tensions, and avoid notes worked out for every
common chord type — written for musicians with ordinary theory background and
no prior exposure to post-tonal thinking.

Any advice on how to make these examples actually sound
good?

Be very conscious of keeping the velocity even across each example
— very little change in loudness or attack from note to note. This isn’t easy to do
but will really help make them sound good. Chapter 7 in Trichord Pairs, and Chapter 9 in
Trichord Pairs 2 and Trichord Sequencing, cover this in more depth.

How do you recommend getting these sweeps and cascades into my
playing?

First I would highly recommend writing music that incorporates these
ideas and writing out solos to play over the music. Not that you want to verbatim play
the solos, but they will help you develop a style with these sounds and give you the
chops you need to execute these ideas in real time.

Could you point me to any examples of you using these sweeps
and cascades?

Yes, I would check out some of my latest recordings. The Cancelwood
Sessions is a good place to start, but I’ve been using these ideas for quite some time so
you will hear them every once and awhile in many recordings and live gigs. Check
youtube.com under my name for more examples.

Could you give me some idea on how to practice sweeps and
cascades?

I would start slow, because you can really hurt yourself if you do too
much too early in your development. If you are a guitarist, be very conscious of your
little finger on your fretting hand — that can get inflamed quite easily from the
stretches used in the sweeps and cascades.

Where is a good place to start with this book?

You can really start anywhere, but my recommendation is to work through each book in order that way you are slowly adding on more material and mastering parts of it as you go.”

Blues Outside the Box — A Trichord-Pair Approach to Superimposing the Blues Scale

Most improvisers meet the blues scale the same way: as one fixed six-note shape, dropped over a dominant chord and left there. Blues Outside the Box starts from a different question — if a six-note scale is really just two three-note cells stacked together, how many genuinely different ways can the blues scale be split? The answer is a clean, closed number: ten. Not a curated subset — every single way to divide its six notes into two trichords, worked out in full and verified against real chord tones and tensions rather than assumed by habit.

Naming the harmony is the easy part. This book pairs that system with a complete mental practice method, physical technique, and macro-pulse rhythmic approach — the same complete-system philosophy behind the trichord-pair approach to major and melodic minor — so the material actually gets into your ear and your hands instead of sitting on the page.

Blues Outside the Box also tackles a question most blues-scale material never addresses directly: the scale’s built-in run of three consecutive half steps. This book shows you exactly when that run should be heard as a chromatic approach-note pattern — the same device bebop scales are built around — rather than three notes each needing to individually justify itself against the chord underneath.

10Trichord pairs — every possible split of the blues scale, no leftover note

4Practice file types — Overview, Sequencing, Scale-Run, and Exercise files

12Keys — every combination fully transposed and ready to read and hear

8Chord types checked note-for-note against every blues transposition

What This System Gives You:

Every Valid Combination — All Ten: Because the blues scale has no leftover note, this isn’t a curated selection — it’s the complete, closed set of every way to split its six notes into two trichords, each with its own contour and color.

A Full Superimposition Analysis: A working appendix checks all twelve transpositions of the blues scale against the chord tones and available tensions of eight common chord types — CMaj7, Cm7, C7, Cm7b5, C7sus4, C-Maj7, Cdim7, and CMaj7#5 — so you know exactly which key to borrow from, and exactly which single note to treat as a passing tone when you don’t get a perfect fit.

The Chromatic-Run Reframe: A clear, practical explanation of why the blues scale’s built-in half-step run is an approach-note pattern rather than a liability, with the bebop-scale connection that makes the idea click.

A Complete Mental Practice Method: Build a stable virtual instrument, fire the same motor pathways as live performance below the threshold of movement, and use the minutes before sleep to hardwire a combination into permanent memory.

Macro-Pulse Rhythm Applied Directly: The anchor-point method that keeps an eighteen-bar sequence, a twenty-four-bar exercise line, or a two-octave scale run from turning into a note-by-note grind.

Technique That Won’t Cost You Your Hands: A resting reference position, forearm-driven mechanics, and the specific hand position that lets you practice this material for years without injury.

Full PDF and MIDI Practice Files: All ten combinations run through all twelve keys, in four different formats — ready to read and to hear.

What’s different from a standard blues-scale resource: most blues-scale material gives you one shape and a handful of licks. This book gives you the complete, closed set of every way that shape can be split into two smaller melodic cells, plus the exact chord-by-chord, key-by-key data on where each transposition actually belongs — not general advice, but a checked-and-verified reference you can act on immediately.

Superimposing the Blues

Really the core of this course is superimposing the blues scale in various ways. One being the use of trichord pairs (triad pairs) to split the blues scale in half and the other is using the blues scale and superimposing it over other key centers.

Advanced Blues Scale

You could think of the melodies found in this course more like SRV meets John Scofield or Mike Stern for tea. Also reminds me Robbin Fords playing. All these great players were pushing the limits and you can too with the melodies contained in this course.

Examples of Exercises Found in Blues Outside The Box

There are four types of files found in the Blues Outside The Box

Blues Scale Runs

Simple List of 10 Trichords Pairs in All Keys

Blues Trichord Pair Exercises

Trichord Sequencing for Blues Scale

Other Exercises found in Harmonic and Melodic Equivalence 21A Course. The whole course is included in this course.

Rather than show you PDFs of the exercises I thought it might be of more value to hear what these exercises sound like in real music. This first example you can hear three of type of exercises presented found in this course. You will hear these lines played by guitar over a bass vamp. I highly recommend you permutate the rhythm within these examples when you add them to your vocabulary.

The are three different Types of Melodies in the example above. The course gives you these types of melodies in all keys. https://muse-eek.com/wp-content/uploads/2026/08/BluesOutsideTheBoxExamples.mp3

The 2nd example let’s you hear what all 12 blues scales sound like over an F bass vamp. I only give you the first page of the example because it’s quite long. I think you can hear from this example that blues scales in any key can work over a one key vamp. By using some of the additional techniques recommended in the book. i.e. Approach Notes in particular allows you to resolve the melodies in awesome ways.

The Example above plays all 12 blues scales against the Key of F. It starts with the key of C. You can hear from this example how all 12 blues scales work over one key center. I think it sounds pretty awesome myself!: https://muse-eek.com/wp-content/uploads/2026/08/BluesOutsideTheBoxExample2AllKeys.mp3

Course Prerequisites & Recommendations:
You don’t need a strong understanding of contextual ear training to start this course, but a foundation in contextual, key-center-based hearing is highly recommended — Appendix A lays out the ear-training approach this book depends on. For optimum results, work through the combinations in Chapter 5 alongside a key-center-producing drone tool. Chapter 3 gives you enough physical technique to work safely through this material, but it isn’t a complete method — pair it with Guitar Technique and Physiology for the full treatment, and see The Sonic Resource Guide for the deepest treatment of pitch class set theory. If you already own Trichord Pairs, this book stands on its own but shares the same underlying practice method, so the two reinforce each other directly.

Frequently Asked Questions

Do I need to already own Trichord Pairs to use this book?

No. Blues Outside the Box is a complete, standalone system built specifically around the blues scale. It uses the same mental practice, technique, and rhythm approach as Trichord Pairs, so if you already know that method, Chapters 2 through 4 will feel familiar — but nothing in this book assumes you own or have read the other title.

What other books do you recommend using alongside this one?

Guitar Technique and Physiology for the full hand-position and picking curriculum, The Sonic Resource Guide for the complete pitch class set theory behind Appendix B, and Ear Training One Note Complete and Contextual Ear Training to build the key-center hearing this whole system depends on.

What should I use to improvise over these combinations?

Get a looper if you can, and build loops using one of the ten trichord pairs as a scale to solo over. If a looper isn’t an option, Jam Tracks Volume One, available on the Muse Eek Publishing website, works well for this — the pairs in Chapter 5 sit especially naturally over static or slow-moving dominant vamps.

How much should I practice these trichord pairs each day?

As a starting point, spend about 30 minutes playing and memorizing a single pair through one key. Then spend another 15 minutes improvising with it — melodically, and with the chords if you play a chordal instrument. That’s a good baseline — build up from there as it becomes comfortable.

Do I need to know pitch class set theory to use this book?

No. Appendix B is a complete primer — prime form, integer notation, and a full chord-tone-and-tension breakdown for eight common chord types — written for musicians with ordinary theory background and no prior exposure to post-tonal thinking.

How is the superimposition analysis in Appendix B actually useful in practice?

It tells you, chord by chord, exactly which key’s blues scale sits entirely inside that chord’s tones and tensions (four such matches exist), and for every chord where no perfect match exists, exactly which single note is the outlier — almost always the b5 — so you know precisely what to treat as a passing tone rather than guessing.

Any advice on how to make these examples actually sound good?

Be very conscious of keeping the velocity even across each example — very little change in loudness or attack from note to note. This isn’t easy to do but will really help make them sound good. Chapter 7 covers this in more depth.

Mental Practice — The Ultimate Operational Manual for Mind-Only Rehearsal

For decades, the dominant music pedagogy has pushed a destructive myth: that mastery requires physical suffering. Musicians lock themselves away for six to eight hours a day, mindlessly repeating scales until their joints inflame. This high-tension physical grinding causes an unspoken epidemic of career-ending repetitive stress injuries.

Your instrument is completely incapable of initiating music on its own. It is a passive interface. It can only execute the precise neurological blueprints sent to it by your brain. If the blueprint in your mind is fuzzy, hesitant, or rooted in straining, your live performance will replicate that chaos.

Mental Practice shifts the bulk of your technical development straight into your mind. By firing your exact motor paths below the threshold of physical movement, you completely eliminate physical wear and tear. This is a highly disciplined, systematic program designed to clean your internal blueprints of all hesitation, allowing your hands and feet to execute music with absolute lightness and ease.

What This Systematic Mental Practice Accomplishes:

Builds the Virtual Instrument: Clear instructions to stabilize a blurry internal canvas into a razor-sharp, hyper-realistic internal map of your specific instrument geometry.

Activates Sub-Threshold Motor Firing: Teaches you to seamlessly coordinate the mechanics of both hands simultaneously using micro-gestures beneath the threshold of physical muscle contraction.

Leverages the Sleep Consolidation Window: Explains how to use strategic 10-to-15 minute pre-sleep rehearsal sessions to force your brain to hardwire complex phrases into long-term memory overnight.

Integrates Essential Prerequisite Filters: Seamlessly combines your mental workouts with Bruce Arnold’s signature Long Line Rhythm macro-pulse feel and core laws of musculoskeletal instrument physiology.

NEW – 4-Limb Drum Set Framework: A dedicated technical module built specifically to help percussionists map four-way coordination and independence entirely in the mind without a drum kit present.

Frequently Asked Questions

What Books do you recommend that I use with this mental practice book?

There are a lot of different books you could use here is a sampling:

1. Speed Demon

2. Modal Sequencing

3. Chopbusters

4. Essential Scales

5. Approach Notes

6. Chord Workbook for Guitar Volume One

Basically any book that has a lot of technical exercises in it. But really you can use this for any aspect of playing music. Memorizing lyrics, stepping through a sequence of guitar pedals, dance steps literally anything!

Is there any correspondence between how much you practice mentally and physically?

Mental practice is exponentially more effective than physical practice so 10 minutes of mental practice is like an hour of physical practice when done correctly.

I read somewhere that you use to do mental practice as you walked between classes at Berklee?

Yes i certainly did and walking is great especially if you do the exercises in your head to the rhythm of your walking pace. Not something you will be able to do right away but getting your mind to work with a physical rhythm that your body is doing is very good. That’s why drummers have such good rhythm skills!

I’m a beginner at guitar. How can I use mental practicing?

well most likely you won’t be able to do the rhythm side of mental practicing for awhile. But if you are learning a scale or a chord imagine what those notes look like on the guitar will greatly improve your progress!

Can mental practice work for anything not just music?

There was a famous Russian study where they had a group of people shoot free throw baskets with a basketball and then another group that laid down at the free throw line and imagined throwing free throw baskets. The people that laid down and imagined did far better when both groups where tested. Yes mental practicing works for anything you want to learn!

You say in the book that it will take time to master the mental practicing. In your experience how long does it take?

Students notice their ability improves in about a week but to get so you are really productive would be about a month of doing it everyday. As you can see from the book there are many other aspects like ear training, rhythm skills that go along with this so if you are deficient in these areas it could take longer.

Greatly appreciate your section in this book on “Context.” I’ve have beaten myself up for years for some of the things that are just context. I actually feel a lot of relief and wish I would have had this book years ago.

Charlie Banacos use to say that learning to play an instrument is like doing 10 years of psycho therapy :). Many problems we hide and don’t reach out to find answers. I’m glad some of the content of this book has helped you. I was lucky to have great teachers as I developed. Of course, wish I would have had them when I was a kid but better late than never!

Speed Demon — Forming New Playing Patterns and Unlocking Intervallic Logic

For years, contemporary instrumentalists have been trapped by visual geometry. Fingers default to the same predictable scale boxes, familiar arpeggio grips, and step-wise linear runs that look neat on the instrument but sound completely uninspired to the listener. Speed Demon changes that by introducing a rigorous, non-linear mathematical permutation system heavily inspired by the legendary jazz educator Charlie Banacos.

By anchoring an unwavering pivot root note (“1”) and relentlessly scrambling the surrounding scale degrees through wide, angular jumps and directional waves, the visual illusions of your instrument dissolve. This course systematically uncovers your technical blind spots and replaces them with an iron-clad, physical map under your fingers.

Seven Levels of Advanced Harmonic and Structural Density

This course spans seven distinct structural layers, systematically pushing your technique through increasing levels of complexity:

Level 1: Diatonic Major Core. Grounds your technique inside the universal major scale template, establishing the initial physical grid.

Level 2: Melodic Minor Shift. Lowers the 3rd scale step to compress your layout and expand modern jazz options over altered dominants.

Level 3: Augmented Second Stretch. Navigates the wide, irregular three-semitone gap of the Harmonic Minor scale at blistering tempos.

Level 4: Hybrid Dark Layer. Blends a bright major triad with a dark minor sixth, challenging your muscle-memory adaptability.

Level 5: Octatonic Interlock. Symmetrical eight-tone diminished layout that completely shifts traditional numbered scale-degree index assumptions.

Level 6: Floating Grid. Symmetrical six-tone Whole Tone profiles that eliminate perfect fourths and fifths, creating smooth, anchorless terrain.

Level 7: Blues Grid – Another six note scale with incredible potential because it is based by key not by chord.

The Banacos Legacy: Built-In 3-Note Pickups

True to the pedagogical philosophy of Charlie Banacos, these exercises are built for metric flexibility and real-world improvisation. Every key signature utilizes an intentional 3-note pickup structure (consisting of an eighth-note rest followed by the last three notes of the pattern) leading directly into the core pattern. This layout forces you to navigate off-beat phrasing, maintain rock-solid rhythm, and accent smoothly across the bar line at high velocities.

How to Use This Course

The practice routine demands absolute cognitive engagement. Dedicate 15 minutes, twice a day, to these exercises. This tightly focused 30 minutes is enough to make profound progress without physical burnout. Work through every pattern across all 12 keys following the strict Circle of 5ths order, training your ears to achieve perfect key retention against the unwavering root anchor.

Example of a Blues Scale in Bb

This example uses a Bb Blues scale and repeats the 2nd measure four times. There are midifiles included that play the 2nd measure 2X or just the single 2 measure one time. This gives you a lot of flexibility. Because you can use a DAW such as Garage Band you can change the type of instrument playing the midi file and also the feel. i.e. making it a swing or straight eighth rhythm.

Keep in mind this is one page of 6 because the sequence is started on all notes of the scale. This gives you a massive amount of examples to get your blues chops screaming fast! If your reading skills are not great memorize the pattern A-M. Start slow, there are midi files so you can control the tempo at all times.

Frequently Asked Questions

I picked up your speed demon course. I am wondering about daily practice routine. I would think to be systematic and cover the entire instrument for phase 1:

1. play through the exercise at a slow tempo with a drone and play along with the midi file. start with ionian. work out the fingerings and picking. Find gaps and problems and fix those in isolation.

2. cycle through the 7 3NPS positions

3. cycle through the 7 modes of the current key

4. cycle keys

Do I have this correct?

Yes that seems like a good approach. I didn’t mention in the book that articulation can also be applied. Like hammer ons, pulloffs or slides on a guitar or tonguing on a wind instrument etc. That said, many people that play fast have very little articulation unless it allows them to play the line faster. Blues guitarists commonly have hammer ons, pulloffs or slides to make a line easier to play.

So take that into consideration but overall start slow figure out how you want to play the line then start speeding it up. One thing you will probably find is as you speed up some of the ways you play something might not work so you will have to adjust along the way

Your productivity always amazes me! Do you think that this course would work well for bass too?

Yes I think it is important for bass players to read treble clef because if you are asked to play the melody to a piece of music it is often given to you in treble clef. I was thinking about making a bass clef version but just short on time right now. If you get the treble clef version I’ll send you the bass clef for free once I make it and of course that is “IF” I make it. Can’t promise right now :)

Why does this course engrave a repeat sign starting at the second bar instead of the first?

This mirrors Charlie Banacos’ exact layout rules. The first measure functions as a 3-note pickup to establish the tempo and physical trajectory off the downbeat. The second measure contains the core four-note speed demon pattern, which repeats exactly 4 times before the double-sided repeat signs move your hands to the next key signature along the wheel.

I don’t know if I have two 15 minutes slots everyday to practice Speed Demon. Do you have any recommendations for someone in my situation?

One of the best things you can do is use my Mental Practice Course. Charlie Banacos always told me to do as much mental practice as I can. You don’t need your instrument you just need to imagine the instrument in your mind and in this case practice the melodies but Mental Practicing can be used for pretty much anything.

So check out the Mental Practicing for Musicians Book, but remember, like anything you practice, it takes time to get good at it. You should find within a week or so you will see progress. I often give this idea to my students where I’d give them a hard melody and have them go home for a week and practice it, but only in their head. Then when they came for their next lesson I’d had them play it for the first time on their instrument. Many reported that they could play the melody faster than anything they had ever played and they could recall it weeks later so it was deeply embedded. Mental practicing is powerful stuff and all the great musicians I know do it everyday!!

I’m a beginner. Can I dive straight into Level 5 Symmetrical Diminished or Level 6 Whole Tone?

It is highly recommended that you master the levels in sequential order. Symmetrical layouts completely alter your finger placement choices because they break away from traditional seven-note major scale spacing. Level 1 Major and Level 2 Melodic Minor build the foundational muscle memory and relative pitch strength required to navigate those advanced grids safely. That said, if you are a more advanced player or let’s say just a blues player and that is all you want to play then by all means jump right to what interests you the most or fits into your style.

Why are there no audio mp3 play-alongs included in this version of the book?

By providing high-fidelity, unfolded Type-1 standard MIDI files instead of static audio tracks, you gain total freedom. You can import these custom MIDI patterns directly into any DAW or software sampler (like Kontakt) to instantly pick your own favorite instrument sounds, apply custom swing adjustments, and scale the playback speed to any tempo that fits your immediate practice needs. I should also mention there are a ton of midi to mp3 conversion programs out there so if you prefer an mp3 then they are pretty easy to make. Just remember it will be at one tempo only so you would have to make multiple mp3s to slowly speed up the lines.

Does this book include guitar tablature staves underneath the standard music notation?

No. This course is strictly note and interval-agnostic, using clean treble-clef notation to ensure it functions perfectly for guitarists, pianists, saxophonists, and violinists alike. Removing specific instrument finger-shapes forces you to learn the actual layout of the pitches across your entire instrument, effectively shattering your reliance on visual geometric box patterns. That said, I certainly can understand if you seldom have to sight read on the guitar you will have difficulty getting started with this course. I would still recommend you get the course and take time to figure out and memorize each melody. They are short so it should take too long to get it into your memory. Then start using the 4x midi files and build from there. It will work it just takes a little extra time for you to memorize each melodic line

I’m not sure I understand if you just practice the written parts with metrodrone and gradually speed the exercises up or do you always play with the midi file and speed that up. Also does matter what strings sets you plays on or is ok to play them in random positions the neck, ex. Around 3rd fret area etc. ?

You could approach this in multiple ways:

1. Use only a Metrodrone and speed up the exercise over time
2. Use the midi file and speed that up over time. This is good because it helps you hear if you are making a mistake.

3. For a guitarist there will obviously be many places to play the exercise. I would pick just one and speed that up then move to another position over time.

4. For guitarists I wouldn’t pick a position that is very low on the neck because it is more common to play in higher positions when soloing.

5. Try to play through the entire exercise as a goal.

6. Use the Mental Practice course so that you can also do this in your mind.

Segmenting Bebop Scales with Approach Notes by Bruce Arnold for Muse Eek Publishing Inc. uses the same 124 octatonic (eight note) scales as the “Segmenting Bebop Scales” course. The main difference is the inclusion of 11,904 PDFs and Midi files for the exercises and an explanation of approach notes. “Segmenting Bebop Scales with Approach Notes” will of course get you using approach notes but it will also change your ability to play over chord changes and more importantly, how it will change your phrasing. This course is part of a series of books on octatonics

The use of approach notes with these segmented Bebop scales requires a whole new set of skills which will become apparent as you read through the course. If you haven’t worked with approach notes previously you will find this will be a pretty step learning curve especially when you start applying these figures within real music.

I spent many years working on the similar rote exercises as found in this book. I also spent a lot of time applying these figures to jazz standards. Most of the chord progressions I used were from the Bebop lexicon; songs such as “Confirmation,” “Donna Lee,” and Rhythm Changes. It is also a great idea to play these progression in all 12 keys.

You will quickly find that not only do these segmented Bebop scales with approaches gives you a strong “Jazz Sound” but they also help your understanding phrasing in a whole new way. By anticipating the segmented Bebop line you create a whole new way to phrase. More on this in the course.

With the addition of this course you now have three method books that you can use to get a deeper understanding of Bebop scales and two different ways to play them, with and without approaches.

It’s also important to do some ear training with these “Segmenting Bebop Scales with Approaches”. My teachers had me play but also sing these segmented Bebop scales with approaches all in one key. So for instance, if you were playing these over “Donna Lee” you would sing all the segmented scales in the key of Ab. This will not be easy for most musicians but will really ingrain the information and help improve your key retention.

Below is an excerpt from the Foreword of “Segmenting Bebop Scales with Approach Notes”

“Segmenting Bebop Scales with Approach Notes” is very similar in written content to the “Segmenting Bebop Scales” course. The main difference is the inclusion of 11,904 PDFs and Midi files for the exercises and an explanation of approach notes. Although the application of Bebop scales with approaches is very similar to the directions used for the “Segmenting Bebop Scales” course, one of the crucial differences is how this course will change your ability to play over chord changes and more importantly, how it will change your phrasing.

The use of approach notes with these segmented Bebop scales requires a whole new set of skills which will become apparent as you read through the course. If you haven’t worked with approach notes previously you will find this will be a pretty step learning curve especially when you start applying these figures within real music.

I spent many years working on the similar rote exercises as found in this book. I also spent a lot of time applying these figures to jazz standards. Most of the chord progressions I used were from the Bebop lexicon; songs such as “Confirmation,” “Donna Lee,” and Rhythm Changes. It is also a great idea to play these progression in all 12 keys.

You will quickly find that not only do these “Segmenting Bebop Scales with Approach Notes” gives you a strong “Jazz Sound” but they also help your understanding phrasing in a whole new way. By anticipating the segmented Bebop line you create a whole new way to phrase.

With the addition of this course you now have three method books that you can use to get a deeper understanding of Bebop scales and two different ways to play them, with and without approaches.

It’s also important to do some ear training with these segments. My teachers had me play but also sing these segmented Bebop scales with approaches all in one key. So for instance, if you were playing these over “Donna Lee” you would sing all the segmented scales in the key of Ab. This will not be easy for most musicians but will really ingrain the information and help improve your key retention.

This course contains a lifetime of practice. Mastering 124 segmented Bebop scales will take many years. I recommend you use some of the popular Bebop scales first and then branch out over time to some of the more esoteric examples.

What people are saying:

OK I got a sneak preview of this course from Bruce. This is a heavy weight look at the ultimate way to play Bebop Scales. Bruce said he learned the concept from the great tenor player Jerry Bergonzi back in the day. Bruce Arnold also said it really helped him to play over jazz tunes but also totally revolutionized his phrasing. Highly recommend!. J. Johnson

Totally killing course. I think this is my favorite in the Bebop Series. I’ve worked with Bruce’s Approach Note course so this is really great to dig into some more esoteric Bebop Scales. Love the idea of using these types of scales in a more modern way. T. Barnett

OK this is it. If you want to get Bebop Scales into your playing this mammoth undertaking will get you there. The hippest thing for me is taking some of these esoteric Bebop scales and applying them to dominant chords. Holy Crap that sounds great! A. Victors
