About the D Composite Blues scale
D 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 D, E, F, F♯, G, A♭, A, B, and C. The formula is W H H H H H W H W.
Also called Nine-Note Blues and Blues Enneatonic.
The open-string notes E, A, D, G, and B all sit inside D Composite Blues. On guitar, the deepest D within reach is the 5th fret of the A string.
