About the A flat Whole Tone scale
A flat Whole Tone is used for dream sequences, impressionist music and solos over dominant chords. Think of it as a scale of nothing but whole steps, floating with no clear home. It is A♭ Prometheus with the sixth lowered.
Its notes are A♭, B♭, C, D, F♭, and G♭. The formula is W W W W W W.
Also called Auxiliary Augmented and Messiaen Mode 1.
A♭ Whole Tone uses three black keys on the piano, A♭, B♭, and G♭. Its raised fourth lands on the white key D.
