About the A flat Tritone scale
A flat Tritone is used for jazz and film music that wants a symmetrical, unstable color. Think of it as a symmetrical six-note scale built on the tritone. It is A♭ Blues Diminished with the third lowered.
Its notes are A♭, A, C, D, E♭, and G♭. The formula is H 1½ W H 1½ W.
A♭ Tritone uses three black keys on the piano, A♭, E♭, and G♭. That raised fourth spells out to the white key D.
