About the A sharp Two-semitone Tritone scale
A sharp Two-semitone Tritone is used for experimental and cinematic writing. Think of it as a symmetrical six-note scale with pairs of half steps.
Its notes are A♯, B, B♯, E, E♯, and F♯. The formula is H H 4 semitones H H 4 semitones.
E and B are open guitar strings that sit inside the scale, ready to drone under a riff. On guitar, the deepest A♯ within reach is the 1st fret of the A string. Placed at the first fret, a capo lets A♯ Two-semitone Tritone be played with A-shape fingerings.

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.
