SCHOOL OF SCALES
TETRACHORDS
Explore a system of colour-coded tetrachords (four note mini-scales)!
SCALE MACHINE V1
Combine two tetrachords to create four heptatonic scales!
SCALE MACHINE V2
Combine 16 tetrachords to create 256 heptatonic scales!
SCALE MACHINE V3
Combine 26 tetrachords to create 676 "scales"!
The 26 tetrachords are required to create the 266 heptatonic scales
(without an interval greater than an augmented 2nd / three semitones).
PARENT SCALES
Heptatonic scales come in groups of seven modes, called a "Modal Class"
One of these modes can be selected as the "Parent Scale" to aid learning!
Eight Parent Scales serve as a template to learn 266 heptatonic scales (per key)!
56 MODES
Explore and listen to the 56 modes of the Eight Parent Scales (seven modes each)

SCALE INVERSIONS
Each scale, when reversed, is another scale!
This concept is related to Parent Scales and Negative Harmony.
Six heptatonic scales (without an interval greater than an augmented 2nd / three semitones) are palindromic (self-inverse) .
The six self-inverse scales are created by the six tetrachords with a Perfect 4th.
