A♯ harmonic minor

A♯1B♯2C♯♭3D♯4E♯5F♯♭6G𝄪7

Natural minor with the seventh raised, which buys a leading note and pays for it with a step and a half between the sixth and seventh.

The same sounds spelled from the other side are B♭ harmonic minor.

Written out

Fig. 2 · A# harmonic minor, ascending

Every accidental is written in, rather than left to a key signature, so the letters can be read one at a time.

What is true of it

A♯ harmonic minor is A♯, B♯, C♯, D♯, E♯, F♯ and G𝄪, and back to A♯.

Its steps are W – H – W – W – H – W+H – H, where W is a whole step and H a half.

Written correctly it needs 8 alterations, G𝄪 among them. That is what the letters force, and it is also why nobody writes music in this key: the same notes spelled from the other side are easier to read.

On the same tonic, A♯ natural minor differs from it by exactly one note.

Across the first twelve frets of the ukulele its notes fall in 30 places, which is what makes a scale a shape rather than a list.
