ukulele scale
G♭ Hungarian minor
Harmonic minor with a raised fourth, which puts a second augmented second in the middle of the scale.
The same sounds spelled from the other side are F♯ Hungarian 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♭ Hungarian minor is G♭, A♭, B♭♭, C, D♭, E♭♭ and F, and back to G♭.
Its steps are W – H – W+H – H – H – W+H – H, where W is a whole step and H a half.
Written correctly it needs 7 alterations, B♭♭ and E♭♭ 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♭ harmonic 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.
