How to read the shapes
Circle / straight line — Unison or octave (1:1, 2:1). The two voices agree.
Figure-eight — Octave (2:1). One voice twice the other.
Pretzel / 3-loop knot — Perfect Fifth (3:2). The most stable "open" shape.
Tall woven lattice — Fourth (4:3) & seconds — denser as the ratio gets complex.
Dense criss-cross box — Minor/Major 2nds & 7ths (9:8, 15:8). High-tension intervals.
Rotating / drifting figure — The voices are detuned; rotation speed = beat frequency.
Teal / green — the interval is close to pure (low strain).
Shifting to amber/ember — straining away from pure tuning.
Brighter, larger figure — louder moment (the shape "breathes" with volume).
The figure is the interval, drawn. More lobes = more complex ratio. A clean, slow, teal loop is consonance you can see; a fast, dense, ambering tangle is tension made visible.
