C Rock 'n' Roll — Organ

C Rock 'n' Roll 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.

Major pentatonic with a b3 rubbed against the natural 3 — bright and bouncy with a bluesy smirk. Playful, swinging, and built for boogie riffs.

Heard in: Fifties rock, rockabilly, boogie-woogie, Chuck Berry-style riffs, and jump blues.

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.
