Gb Harmonic Major on Guitar
Gb, Ab, Bb, Cb, Db, Ebb and F are the notes of the Gb harmonic major scale. A double flat in Ebb makes it unusual, so most guitarists read F# harmonic major in practice. The sound is identical, and the root is on the 2nd fret of the low E string.

Structure
Gb harmonic major scale notes:
How the harmonic major scale is built:
The harmonic major scale is built from the degrees 1 2 3 4 5 b6 7, which gives the step pattern W-W-H-W-H-W+H-H (W = whole step, H = half step).
Counting in semitones from the root: 0, 2, 4, 5, 7, 8, 11. That makes it a 7-note scale.
It is the parent scale of its own modal family.
