guitar 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 G♯ 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.
On the same tonic, A♭ Lydian differs from it by exactly one note.
Across the first twelve frets of the guitar its notes fall in 43 places, which is what makes a scale a shape rather than a list.
