ukulele scale
A♯ Lydian dominant
Raised fourth and flattened seventh at once — the fourth mode of melodic minor.
The same sounds spelled from the other side are B♭ Lydian dominant.
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
A♯ Lydian dominant is A♯, B♯, C𝄪, D𝄪, E♯, F𝄪 and G♯, and back to A♯.
Its steps are W – W – W – H – W – H – W, where W is a whole step and H a half.
Written correctly it needs 10 alterations, C𝄪, D𝄪 and 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, A♯ Lydian differs from it by exactly one note.
Across the first twelve frets of the ukulele its notes fall in 31 places, which is what makes a scale a shape rather than a list.
