F Blues — Organ

F Blues carries 6 notes per octave (blues family), drawn here straight onto the Organ'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 Organ ignores touch: every key speaks at one level, so evenness here is about timing alone — the maps and the audio keep that honest.
