Gb Phrygian Dominant on Guitar
Gb, Abb, Bb, Cb, Db, Ebb and Fb form the Gb Phrygian dominant scale. Three double flats make it awkward, which is why most players read F# Phrygian dominant instead. The two sound identical, and the root is the 2nd fret of the low E string.

Structure
Gb phrygian dominant scale notes:
How the phrygian dominant scale is built:
The phrygian dominant scale is built from the degrees 1 b2 3 4 5 b6 b7, which gives the step pattern H-W+H-H-W-H-W-W (W = whole step, H = half step).
Counting in semitones from the root: 0, 1, 4, 5, 7, 8, 10. That makes it a 7-note scale.
It is mode 5 of the Harmonic Minor Scale, so both scales share the same notes from a different starting point.
It is also known as Jewish Scale, Ahava Raba, Freygish and Spanish Phrygian.
