Exploring Diatonic and Modal Collections in Music Theory
Discover the intricacies of diatonic and modal collections in music theory, including the major scale rotations, anhemitonic pentatonic collections, symmetrical scales, and more. Explore the relationships between different modes and scales, as well as unique combinations like the acoustic scale. Dive into the world of modal IDs, octatonic scales, and hexatonic scales for a comprehensive understanding of musical structures and patterns.

Diatonic/Modal Collections The major scale in successive rotations, therefore still diatonic; C major=C Ionian; beginning on D, Dorian; on E, Phrygian; on F Lydian; on G Mixolydian; on A, Aeolian; on B, Locrian. As with the major and minor scales, there are twelve forms (twelve distinct collections) of each mode.
Diatonic/Modal Collections Ionian Dorian with mm7 chord) Phrygian Lydian Mixolydian Mm7 chord) Aeolian Locrian 2-2-1-2-2-2-1 (Major Scale) 2-1-2-2-2-1-2 (symmetrical; associated 1-2-2-2-1-2-2 2-2-2-1-2-2-1 2-2-1-2-2-1-2 (begins with 1, flat 7th) (major with #4) (major with flat 7th; associated with 2-1-2-2-1-2-2 1-2-2-1-2-2-2 (Natural minor) (begins with 1; flat 5th and flat 7th)
Anhemitonic Pentatonic Collections No half steps, two non-consecutive thirds: 2-2-3-2-3. Rotations of standard C anhemitonic pentatonic
More modal IDs This is the acoustic scale - not covered in your text C-D-E-F#-G-A-Bb-C 2-2-2-2-1-2-1-2 What two scales seem to combine here?
Symmetrical Scales 1. Even and Odd Whole Tone
The Octatonic Scale OCT (0,1) = Octatonic collection with pc 0 & pc 1
The hexatonic scale S-m3-S-m3-S-m3
The hexatonic scale transpositional combination
