F Locrian — Organ

F Locrian carries 7 notes per octave (modes family), drawn here straight onto the Organ's keys with every root pinned — no tablature in between, the keyboard is the map.

The most dissonant, unstable mode — the tonic chord is diminished (b5), making a true Locrian tonal center rare. Used for color and passing harmony.

Heard in: Metal riffs, jazz (half-diminished ø7 chords in ii°7 – V – i), horror and tension film scores.

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.
