C Whole Tone — Terz Guitar

C Whole Tone is 6 notes per octave (symmetric family), drawn here as position boxes on the Terz Guitar's GCFA#DG grid with the root flagged in each — learn one box deeply, then let the overlaps carry you into the next.

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 GCFA#DG grid is fourths with one major third at A#–D, so every box crossing that pair shifts up a fret — the maps draw the kink where it happens instead of pretending the neck is regular.

Play each box top to bottom until the roots feel like home base, then practice crossing between boxes mid-phrase — neck freedom is exactly that crossing, nothing more.
