Gb Dorian Mode for Guitar
The Gb Dorian scale reads Gb, Ab, Bbb, Cb, Db, Eb and Fb. It comes from Fb major and needs a double flat, so practical charts use F# Dorian instead. Both have the root on the 2nd fret of the low E string and sound the same.

Structure
Gb dorian scale notes:
How the dorian scale is built:
The dorian scale is built from the degrees 1 2 b3 4 5 6 b7, which gives the step pattern W-H-W-W-W-H-W (W = whole step, H = half step).
Counting in semitones from the root: 0, 2, 3, 5, 7, 9, 10. That makes it a 7-note scale.
It is mode 2 of the Major Scale, so both scales share the same notes from a different starting point.
