About the G Composite Blues scale
G 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 G, A, B♭, B, C, D♭, D, E, and F. The formula is W H H H H H W H W.
Also called Nine-Note Blues and Blues Enneatonic.
Five open-string notes belong to G Composite Blues, namely E, A, D, G, and B. On guitar, the deepest G within reach is the 3rd fret of the low E string. The mode runs a complete octave from root to root inside the first three frets.
