About the B flat Tritone scale
B 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 B♭ Blues Diminished with the third lowered.
Its notes are B♭, C♭, D, E, F, and A♭. The formula is H 1½ W H 1½ W.
B♭ Tritone draws two black keys from the piano, B♭ and A♭. Its raised fourth lands on the white key E. This mode lines up four white keys back to back.
