Gb Harmonic Minor on Guitar
Gb harmonic minor is spelled Gb, Ab, Bbb, Cb, Db, Ebb and F. Both Bbb and Ebb appear, and a key signature with nine flats does not exist, so players read it as F# harmonic minor. Nothing changes on the neck, where the root is the 2nd fret of the low E string.

Structure
Gb harmonic minor scale notes:
How the harmonic minor scale is built:
The harmonic minor scale is built from the degrees 1 2 b3 4 5 b6 7, which gives the step pattern W-H-W-W-H-W+H-H (W = whole step, H = half step).
Counting in semitones from the root: 0, 2, 3, 5, 7, 8, 11. That makes it a 7-note scale.
It is the parent scale of its own modal family.
It is also known as Aeolian Maj 7.
