A RATIO OF

3 : 2

C + G

HARMONIC CONTROLS

Frequency / Speed 261.6 Hz (Pitch)

💡 < 20 Hz: Polyrhythmic clicks. 20–30 Hz: Clicks stop and fuse into tone! > 30 Hz: Pure musical pitch.

Slow-mo 4.0 s / period real time

💡 Up to 30 Hz the figure moves in real time with the sound. Above, it is the true motion slowed down so one full cycle of the chord takes this long.

Live MIDI Keyboard

💡 Play chords on a real keyboard: the header, piano, figure and tunnel follow. In Just Intonation each chord is retuned to pure ratios above its lowest note.

Phase Offset (φ) 0.00 rad

💡 Phase Offset (φ): Adds a relative phase to the upper voices. φ = 0 is the clearest view of the figure; sweeping it rotates the figure like a turning 3D wireframe, and at some phases it really collapses into a back-and-forth arc for an instant. Acoustically, human ears are phase-deaf to isolated pitch (Ohm's Law), but phase shifts rhythmic click syncopation (< 20 Hz) and creates audible stereo spatial widening!

Phosphor Persistence 1.0 s

💡 How long the trace keeps glowing in the X-Y scope and the 12-TET Full Loop. Live Trace keeps everything (∞); the faint ghost always shows the complete figure.

Time Tunnel · Depth / Speed 2.00 /s

History length 8.0 s

💡 ⏳ Time Tunnel: the current figure sits at the front and every past moment slides back into depth and fades. With media it follows the track's clock (pause freezes it, seeking clears it).
