D Whole Tone — Organ

D Whole Tone carries 6 notes per octave (symmetric family), drawn here straight onto the Organ's keys with every root pinned — no tablature in between, the keyboard is the map.

Weightless and dreamlike — six equal whole steps with no leading tone, so nothing pulls anywhere. Blurry, floating, and faintly unsettling, like a dream sequence.

Heard in: Impressionist piano (Debussy's "Voiles"), Thelonious Monk's runs, dream-sequence film cues, and the augmented and 7#5 chords it fits in jazz.

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.
