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.
E, D, and B are open guitar strings that sit inside B♭ Tritone, ready to drone under a riff. Down at the 1st fret of the A string lies the lowest B♭ a guitar can play. The mode plays in open position, a whole octave of the scale falling within the first three frets.

Playable shapes for this scale up the neck. Tap any note to hear it.
6-position system
6 four-fret boxes, one per scale degree, each a single hand position with almost no shifting. The jazz and classical way, from William Leavitt's Berklee method. This scale is symmetric, so the same box shape repeats up the neck.
