How many different diminished scales are there?
It is easy to prove that there are only 3 different diminished scales. Every diminished scale contains 8 consonant chords and includes, for each of them, its corresponding relative chord (Major or minor) and its parallel chord (that is, the one obtained by changing the mode).
Why are the only 3 diminished scales?
Because of their symmetry, there are only 3 diminished scales and only 2 whole tone scales! ... Each of the 3 diminished pitch collection (scales) can start (and end) on 8 different notes, corresponding to eight different chords (4 diminished chords and 4 “7(b9)” or “13(b9)” chords).
What are the 3 diminished chords?
There are three types of diminished chords: Diminished triads, half diminished, and diminished 7th, which is also called a fully diminished chord. The diminished triad is what naturally occurs on the 7th degree of the major scale. It's 1-f3-f5.
How many different Octatonic scales are there?
In classical theory (in contrast to jazz theory), this scale is commonly called the octatonic scale (or the octatonic collection), although there are a total of 42 enharmonically non-equivalent, transpositionally non-equivalent eight-note sets.
