Harmonic and Melodic Equivalence V1 Two Triad Pair by Bruce Arnold
Part of the Harmonic and Melodic Equivalence Series
Harmonic and Melodic Equivalence V1 Two Triad Pair is part of a series of books on Pitch Class Set Improvisation called Harmonic and Melodic Equivalence. V1 Two Triad Pair is part of the Harmonic and Melodic Equivalence Series which explores over 40 different three note pairs that I’ve used in compositions and improvisations. To see all volumes follow the link to explore each volume and hear examples from each course as well as finding links to compositions that I’ve written using each combination.
This Pitch Class Set Improvisation course is divided up into two sets of exercises written in treble and bass clef. The 1st set of exercises gets gradually harder but also more musical. Depending upon your musical skills you can start anywhere you want but for beginners I would recommend starting from the 1st exercise of the five.
The 2nd set of Pitch Class Set Improvisation exercises are called “Atomic Scales.” These exercises are a technical exercise that really helps you to learn these ideas but also sound great as a melody right off the bat. There are 6 different types of “Atomic Scales” exercises in this course. You don’t have to play every exercise in every key. But doing this will greatly increase the likelihood of you using it in real music in the future. Below is a listing of the exercises found in this course:
Below is an explanation for each set of the 5 different exercises found in this course. All exercises include MP3s as well as midi files so that you can hear and play these Pitch Class Set Improvisation exercises at any tempo as well as versions in all 12 keys.
Below is an explanation for each set of the 6 different atomic scale exercises found in this course. Three octave sequences that move back and forth between the two 3 note groups are presented in six different configurations.
These Pitch Class Set Improvisation exercises are highly melodic and can be used verbatim as melodies when soloing. If we thought of the three notes as A,B,C then there would be six different ways to combine these notes. i.e. ABC, ACB, BAC, BCA, CAB and CBA. All exercises include MP3s as well as midi files so that you can hear and play these exercises at any tempo as well as versions in all 12 keys.

Additional Information for Harmonic and Melodic Equivalence V1 Two Triad Pair:
I’m looking forward to digging into these Harmonic and Melodic Equivalence courses. They are bit size windows into the use of 3 note groupings over many musical situations. I’m inspired already! J. Ogland
I own most of Mr. Arnold’s pitch class set books. This series really goes to the heart of Mr. Arnold’s explorations in this field. I like that it explores just one region at a time but also gives you enough information to dig deeper if you so desire. K. Franklin
This is one of the few places I’ve found where there are exercises that aren’t just a series of eighth notes void of rhythm. While there are some exercises like that in this book the level 5 exercises incorporate rhythm which is essential in making musical sense out of these ideas. I also love the fact that there are midi files for every exercise. That is very helpful! W. Harris
Hey Bruce, greatly appreciate you including the bass clef versions of these exercises in the course. I hate it when you have to buy a separate book just to get the bass clef exercises. I play bass and guitar so you can see my dilemma. I love the ideas you present in this book. Real nuts and bolts applications of materials that are usually thought of as avant garde. Using 013’s as a V7 to I progression. Brilliant! A. Wadsworth
