Dictionary: Ab Major Scale

From this four-flat scale, we can derive the modes Ab Ionian, Bb Dorian, C Phrygian, Db Lydian, Eb Mixolydian, F Aeolian, and G Locrian.  In the table below, the obviously key-appropriate chords are to the left, and some somewhat off-key triads that could work in transition are to the right:

Ab	Fm	Gdim	Abaug
Db	Bbm	Dbm	Bbdim
Eb	Cm	C	Edim
