D Blues — 4-Voice Polysynth

The D Blues lit key by key — roots pinned, degrees named, audio ready.

D Blues carries 6 notes per octave (blues family), drawn here straight onto the 4-Voice Polysynth's keys with every root pinned — no tablature in between, the keyboard is the map.

The minor pentatonic with a b5 "blue note" wedged in — that one extra note adds grit, tension, and a sly, vocal quality. Tough, expressive, and unmistakably bluesy.

Heard in: Blues, rock, jazz, rhythm and blues, and boogie-woogie — Delta and Chicago blues, Hendrix, Clapton, Stevie Ray Vaughan.

The 4-Voice Polysynth answers touch, so practice these maps at more than one dynamic — the pattern is the same, but the hand that plays it soft and loud owns it twice.
