Polyrhythm Visualizer

Compare two to four evenly subdivided rhythms over one shared cycle using an exact LCM grid.

Audio is opt-in: no sound starts until you press Start audio. Keep volume comfortable. Core rhythms use even subdivisions only; no Euclidean distribution is implied. Reduced-motion preferences disable moving playheads while retaining tables and patterns.
