Can I use this polyrhythm tool for real practice?

Yes. The tool includes tempo control, count-in, mute controls, separate sounds, visualizations, shareable links, MIDI export, and a downloadable practice pack.

Is this polyrhythm generator free?

How do I practice a 3 against 2 polyrhythm?

Start slowly, hear the two-pulse side alone, add the three-pulse side, watch where both rhythms land together, then mute one side once the combined pattern feels stable.

How do I count a 5 against 4 polyrhythm?

Use twenty equal slots. The five-pulse side lands every four slots, the four-pulse side lands every five slots, and both rhythms meet again on the next downbeat.

Does it support custom polyrhythms?

Yes. You can start with common ratios such as 3:2, 4:3, and 5:4, then enter custom pulse counts for more advanced cross-rhythm practice.

How to practice 3 against 2

Set the generator to 3:2 at 80 to 100 BPM.
Listen to the two-pulse side until the main beat feels grounded.
Add the three-pulse side and watch the shared downbeat in the visualizer.
Mute one side and keep the missing rhythm internally before speeding up.

How to count 5 against 4

A 5:4 polyrhythm uses twenty equal slots. The five-pulse rhythm lands every four slots, the four-pulse rhythm lands every five slots, and both meet again on the next downbeat.

Start around 60 to 80 BPM, hear the four-pulse side first, then add the five-pulse side until the long twenty-slot cycle feels relaxed.
