piano scale
G♯ harmonic minor
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 A♭ harmonic minor.
Written out
Every accidental is written in, rather than left to a key signature, so the letters can be read one at a time.
The step pattern
What is true of it
G♯ harmonic minor is G♯, A♯, B, C♯, D♯, E and F𝄪, and back to G♯.
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 6 alterations, F𝄪 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, G♯ natural minor differs from it by exactly one note.
