About the D flat Composite Blues scale
D 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 D♭, E♭, F♭, F, G♭, G, A♭, B♭, and C♭. The formula is W H H H H H W H W.
Also called Nine-Note Blues and Blues Enneatonic.
E, G, and B are open guitar strings that sit inside the key, ready to drone under a riff. Down at the 4th fret of the A string lies the lowest D♭ a guitar can play. Placed at the first fret, a capo lets D♭ Composite Blues be played with C-shape fingerings.
