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.
- Say it out loud: the composite of 3:2 has four attacks, so it fits "not-dif-fi-cult". The composite of 4:3 has six, so it fits "pass-the-god-damn-but-ter". Speak it before you play it.
- Combine, listen for both: use a trainer that gives each side its own sound and its own volume, so your ear can keep them apart instead of hearing one composite pattern.
- 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: set both numbers freely, from 2:3 up to complex ratios like 11:8.
- See the ratio, don't just count it: each voice is drawn as its own polygon, and the vertices where the two voices land together are marked permanently — so you can see the structure before you hear it. In 6:4 you see at a glance that it's a 3:2 at double density.
- A third voice: add a third ratio on top of the two, for 3-against-4-against-5 territory.
- Independent sound and volume per voice: mute one side to test yourself, or bring one forward to focus.
- Morph: write a phrase and slide it gradually from one side's pulse to the other's. This is the feature nothing else has, and it's where polyrhythm stops being a trick and becomes feel.
- Swap: flip which voice leads, in one tap. Feeling 3 against 2 and 2 against 3 are different skills.
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 covers both, in two separate modules: this one for polyrhythms, and a dedicated Polymeter module for bars of different lengths running in parallel.

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.
