C♯ melodic minor
Minor third, major sixth and seventh — the ascending form, and the parent of most of the altered sounds below.
The same sounds spelled from the other side are D♭ melodic 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
C♯ melodic minor is C♯, D♯, E, F♯, G♯, A♯ and B♯, and back to C♯.
Its steps are W – H – W – W – W – W – H, where W is a whole step and H a half.
It costs 6 alterations to write — near the limit of what a key signature can carry.
On the same tonic, C♯ major 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.
