F# half-whole diminished scale

8 notes · a ♭9, ♯9 and ♯11 over a natural 13

The same eight notes started a semitone lower, which turns it into a dominant scale: it holds the root, 3rd and ♭7 with the ♭9, ♯9 and ♯11, and unlike the altered scale it keeps the natural 13.

Heard in: Over a 7♭9 or 13♭9; Coltrane, Herbie Hancock, Bond-film harmony.

Twelve frets in standard tuning, high E at the top. Each dot is labelled with its degree rather than its note, because that is the part that moves with you when you play the shape somewhere else. The green dot is the root of whatever is being shown — the scale, or the chord chosen out of it.

Every degree of this scale builds a diminished seventh, because the scale repeats every minor third. There are only three of these scales altogether, and each holds two diminished sevenths whose eight notes are the whole scale.
