Di-Chord Pictograph System — All 11 Di-Chords

Each di-chord has three visual factors: Shape (pulsation)  ·  Shadow (F/O factor)  ·  Color (harmonicity)

Visual Factor Reference

Factor 1 — Shape (Pulsation)

  • Jagged zigzag — Dissonant (8 Hz)
  • Smooth curve — Modal (4 Hz)
  • Flat / gentle — Perfect (2 Hz)

Factor 2 — Shadow (F/O Factor)

  • ← Left arrow — Fundamental side
  • → Right arrow — Octave side
  • ←→ Both — Equidistant (tritone)

Factor 3 — Color (Harmonicity)

  • Dark shade — Non-harmonic
  • Light shade — Harmonic
  • Neutral gray — Neutral / tritone
  • Mid shade — False-harmonic [9]
★ Sprint 1 Focus — Di-chords [3] and [4] (minor 3rd / major 3rd) are the primary learning targets for Sprint 1. The gold border identifies them throughout all course materials.
