Hexatonic Scales: A Complete Guide

A hexatonic scale is a six-note scale. Often referred to as a “hexachord,” it occupies a vital space in modern music theory, sitting between the 5-note pentatonic and the 7-note diatonic (major/minor) scales. This unique structure provides a “signature sound” that is more sophisticated than a pentatonic but more open and transparent than a septatonic scale.

The Influence of Charlie Banacos

Much of the methodology presented here was developed during five years of study with the legendary music guru Charlie Banacos. Charlie used “Double Mambos”—pivoting between two 3-note groups—to teach students how to create modern, non-tertial sounds instantly.

Whether you are a beginner or a professional at Berklee or NYU, these systems break down complex pitch class theory into manageable “pivoting” movements that define your unique voice as a musician.

The 12 Foundational Trichords

In 20th-century Pitch Class Set Theory, every possible 3-note combination can be reduced to one of these 12 “Trichords.” Mastering these is the key to unlocking the hexatonic universe.

Replacing Your “Tired” Old Chords

Instead of playing a standard C Major (C, E, G), try pivoting between 015, 025, or 027 structures. By leaving out the 3rd or adding specific tensions, you create a fresh musical palette that works in any style—from Heavy Metal to Contemporary Classical.

• For Major/Minor sounds: Use 015, 024, 025, or 027.
• For Dominant sounds: Use 012, 013, 014, 016, or 026.
• For Minor 7b5: Stick with 016 to start.

The Aural Path: Ear Training

As Charlie Banacos taught, your ear is your most important vehicle. To master hexatonics, you must recognize these sounds within a Key Center.

The Physical Path: Technique Books

Technique is about developing the “chops” to play what you hear. Our 2026 curriculum includes thousands of permutations based on the Banacos approach.

Historical Context: Jazz & Classical

From McCoy Tyner’s “Passion Dance” (Eb and F triads) to the complex 12-tone rows of Schoenberg and Webern, hexatonics bridge the gap between tradition and the avant-garde. My group “Spooky Actions” has recorded many of these applications to show how a single hexatonic scale can be the foundation for an entire composition.
