About the A flat Composite Blues scale
A flat Composite Blues is used for blues, rock and jazz-blues improvisation. Think of it as the full blues scale, major and minor thirds and the blue note all together.
Its notes are A♭, B♭, C♭, C, D♭, D, E♭, F, and G♭. The formula is W H H H H H W H W.
Also called Nine-Note Blues and Blues Enneatonic.
The key shares D and B with the guitar's open strings. The lowest A♭ on a standard-tuned guitar sits at the 4th fret of the low E string. With a capo at the first fret, A♭ Composite Blues can be played with G-shape fingerings.
