About the D flat Whole Tone scale
D 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 D♭ Prometheus with the sixth lowered.
Its notes are D♭, E♭, F, G, A, and C♭. The formula is W W W W W W.
Also called Auxiliary Augmented and Messiaen Mode 1.
On the piano, the key touches the black keys D♭ and E♭. Notably, the raised fourth falls on the white key G. D♭ Whole Tone includes a stretch of four consecutive white keys.
