About the G flat Bebop Altered scale
G flat Bebop Altered is used for bebop solos over altered dominant chords. Think of it as an altered dominant color built into a bebop scale.
Its notes are G♭, G, B♭, C♭, D♭, D, F♭, and F. The formula is H 1½ H W H W H H.
Also called Bebop Phrygian Dominant and Altered Bebop.
An unfretted guitar already sounds E, D, G, and B from the key. The lowest G♭ on a standard-tuned guitar sits at the 2nd fret of the low E string. Placed at the second fret, a capo lets G♭ Bebop Altered be played with E-shape fingerings.
