Polyrhythm Trainer
Train with common polyrhythms by visualizing two independent beat cycles and hearing how they align over time.
This works right here on your device — nothing gets sent out.
Layered rhythm practice
Hear two cycles together and watch their beats align.
Sample pattern: 3 against 2.
How it works
- Set the top and bottom beat counts for the two simultaneous cycles.
- Choose a tempo for the top cycle and press Start.
- Listen to the distinct tones and follow the highlighted beats until the cycles meet again.
FAQ
What does 3 against 2 mean?
Three evenly spaced beats in one cycle sound over the same duration as two evenly spaced beats in the other cycle.
Does it need microphone access?
No. Audio is generated locally with the browser’s Web Audio API; sound starts only after you press Start.
Why might I not hear the clicks?
Check your device volume and browser audio settings. Some browsers suspend audio until a user presses the Start button.
