C Major9 - Research on Harmony - Variation 6

Seven notes from C1 to D5. The root and ninth interleave: C1, C2, D3, C4, D4, G4, D5 — C and D trading back and forth, the root and ninth in conversation across the registers. Played Lent, mp, legato, in four, the arch rising to D5. No third E, no seventh B — the fifth G appears once at G4, tucked between the alternating C and D notes.

Red and orange alternate through the registers. Black at C1, dark gray at C2, orange at D3, red at C4, orange at D4, red-orange at G4, yellow-orange at D5 — the two warm families weaving through the canvas, each octave a step brighter. The fifth's red-orange sits at the center, flanked by root and ninth on either side.

A study in the interval between root and ninth — the whole step that defines the major ninth's character, C and D echoing each other through five octaves, red and orange interleaving like a conversation that never quite resolves.
