About the A Tritone scale
A 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, B♭, C♯, D♯, E, and G. The formula is H 1½ W H 1½ W.
The scale draws three black keys from the piano, B♭, C♯, and D♯.
