Polyrhythm Trainer — Master Any Ratio
3:2, 4:3, 5:4, 7:4, 5:3 and all combinations. With phrase sequencer integration.
A polyrhythm is two or more independent rhythms played simultaneously — the rhythmic engine behind a huge amount of modern music, from jazz and African percussion to prog metal and electronic music. Practicing them is one of the highest-impact things a drummer or musician can do: it builds independence, internal time, and a deeper understanding of subdivision.
KingMetronome's Polyrhythm Trainer is built for this. Pick your ratio, set your tempo, and hear both sides distinctly — with visual feedback, phrase sequencing, and a build-up trainer to gradually internalize the pattern.

How to practice polyrhythms (and actually feel them)
The trap most musicians fall into is learning the polyrhythm as a pattern — memorizing where each note falls — without ever feeling it as two independent rhythms. That's why even after months of practice, you can play 3:2 but it always feels like one composite rhythm, not two rhythms layered.
The right approach:
- Hands separately at slow tempo (60 BPM): clap or play each side of the polyrhythm alone with a metronome.
- Add a vocal pattern: for 3:2, the mnemonic is "not-dif-fi-cult" where the syllables emphasized differently mark each side. For 4:3, "what at-om-ic" works.
- Combine, listen for both: use a trainer like KingMetronome that pans each side to a different ear or assigns different sounds, so you can audibly distinguish the two.
- Phrase loop: turn the polyrhythm into a 1-bar or 2-bar phrase you can loop indefinitely. Build muscle memory.
- Switch the lead: deliberately shift your mental focus from one side to the other while playing. This is the moment polyrhythm becomes perception, not just execution.
What's in KingMetronome's Polyrhythm Trainer
- Any ratio: 2:3 through 11:8 and custom values.
- Phrase sequencer: link multiple polyrhythms into a sequence — useful for songs and odd-meter pieces.
- Independent volume per side: mute one side to test yourself, or boost one to focus.
- Visual grid: see exactly when each side hits within the bar.
- BPM range 20-300: from slow internalization to performance tempo.
- Accent control: mark the downbeat, accent ghost notes, customize the click pattern.
Polyrhythm vs. polymeter — common confusion
These get mixed up all the time. The difference:
- Polyrhythm: two rhythms within one bar. 3 notes vs 2 notes in the same time span.
- Polymeter: two different bar lengths happening simultaneously. 4/4 against 5/4 takes 20 beats to realign.
KingMetronome's polyrhythm module handles both — set independent meters per side, and the app shows you the resolution cycle.

FAQ
What is a polyrhythm?
Two or more independent rhythms played simultaneously where the underlying pulses don't share a simple subdivision. The simplest is 3:2 — three notes in one hand against two in the other within the same time span.
How do I practice 3 over 2 polyrhythm?
Start each hand alone with a metronome at 60 BPM. Use the mnemonic "not-dif-fi-cult" to combine them. Once that locks, increase tempo gradually. A trainer like KingMetronome plays each side with a distinct sound so you can hear them as independent.
What is the hardest polyrhythm?
Difficulty scales with ratio complexity. 5:4 and 7:4 challenge most players; 7:5, 11:8 and custom prime ratios are expert-level. The real difficulty isn't playing them — it's feeling them as two distinct rhythms rather than as a single composite pattern.
Polyrhythm vs polymeter — what's the difference?
Polyrhythm: two rhythms inside one bar. Polymeter: two different bar lengths running in parallel. Polyrhythms resolve within one bar; polymeters take multiple bars to realign.
