Polyrhythms for Drummers: 3:2, 4:3 and Beyond
A polyrhythm is two different groupings happening at the same time — three against two, four against three — and it is the one technique where counting is genuinely useless. The only way to play a polyrhythm is to feel both layers at once, which is why it takes so long and why it is so satisfying when it clicks.
The short answer
The most useful polyrhythms for a drummer are three.
3:2 — three evenly spaced notes across the same time as two. The most common, and the foundation of most Latin and African-derived feels.
4:3 — four against three. The classic "four over three" that appears in every style.
5:4 — five against four. Less common and considerably harder.
The numbers are a ratio of groupings, not a tempo. 3:2 means: while the other layer plays two evenly spaced notes, you play three evenly spaced notes in the same total time. When both layers restart together, the cycle is complete.
How 3:2 actually works
Take a bar of music and divide it into six equal parts. That is the common ground both layers can use.
The two-side plays on parts 1 and 4.
The three-side plays on parts 1, 3, and 5.
Both hit on part 1, and the three-side has an extra note between. That is 3:2.
The practical drill: count "one-two-three, one-two-three" with the hands playing on every count and the feet playing on 1 and 4 of the six. The feet are playing two, the hands are playing three, and the cycle repeats every six.
The reverse — hands on two, feet on three — is the same relationship from the other side, and it is worth practising both.
Why counting fails and what to do instead
A polyrhythm cannot be counted as a single stream because there is no single stream. Any attempt to count it produces one layer being accurate and the other being approximate.
Three workable approaches, in order of effectiveness.
Physical anchoring. Play the two-side with a limb that has a natural pulse — the hi-hat foot, usually — and let the three-side ride on top. The foot holds the reference and the hand is free to be uneven in the other layer's terms.
Speaking it. Say the two layers as syllables. For 3:2, "one-two-three, one-two" where the words overlap in a specific pattern. Saying it out loud before playing it is genuinely effective, and it is the method most African and Latin traditions use to teach these patterns.
Slow and mechanical first. At a very slow tempo, the polyrhythm becomes a sequence of individual events rather than two simultaneous meters, which lets you learn the order before trying to feel it. This is the step people skip.
The common polyrhythms and where they appear
3:2. The backbone of Afro-Cuban music, and present in most Latin grooves. Also the basis of the standard triplet feel over a duple pulse. See Latin drum grooves.
2:3 (the same relationship inverted). Extremely common in gospel and contemporary church drumming, where the hands play a triplet-based pattern over a duple kick. See gospel drum chops.
4:3. Common in jazz and progressive music. Four evenly spaced notes against three.
5:4 and 7:4. Appear in progressive rock and in modernist composition. Rarely needed in popular playing.
6:4 (which is 3:2 doubled). Common in drumline and in any music with a both-hands-and-feet pattern that spans a longer cycle.
A method that works
Four stages, and the first one is the one that matters.
Stage one: learn it as a sequence. At 50 BPM, play the polyrhythm slowly enough that you can identify each event in order. For 3:2, that is: hands, hands, feet, hands, feet, hands — six events. Play them one at a time, slowly, naming them. Do this until the sequence is automatic.
Stage two: speed it up until the layers separate. Increase the tempo until the ear starts hearing two layers instead of six events. This usually happens somewhere between 70 and 90 BPM, and it is a distinct perceptual shift rather than a gradual improvement.
Stage three: apply it to a groove. Take the 3:2 and put it in a musical context — a Latin groove, a shuffle with a polyrhythmic kick, or a gospel pattern. The technique is not worth having outside a groove.
Stage four: improvise with it. Play the polyrhythm and vary one of the layers. This is where it becomes a musical tool rather than a party trick.
Most of the time goes into stage one and it feels like nothing is happening. That is normal.
The 4:3
Four against three follows the same logic with a longer cycle. Divide the bar into twelve parts.
The three-side plays on parts 1, 5, and 9.
The four-side plays on parts 1, 4, 7, and 10.
They coincide only on part 1 of each twelve-part cycle.
The reason 4:3 feels harder than 3:2 is that the cycle is longer — twelve parts rather than six — so the coincidence point is further away and it is easier to lose track.
A useful trick: play 4:3 as a six-part cycle offset. Practise 3:2 first until it is solid, then add a note. The mechanical relationship is the same; only the length changes.
Making it musical
A polyrhythm played as an exercise sounds like a metronome malfunction. Three ways to make it music.
Put it under a melody. The polyrhythm should be the rhythm section, not the feature. A 3:2 groove under a simple melody sounds sophisticated; the same pattern played alone sounds like a drill.
Use it for a section, not a song. A polyrhythm has an effect because it is different from what came before. Playing it for two minutes produces listener fatigue and a rhythmic texture that stops being special.
Let the other instruments find it. The best polyrhythms are the ones where the bass and the drums lock in a way that takes the audience a moment to notice. That happens when the drummer is playing something the bass can sit inside.
Gear and setup considerations
A polyrhythm spanning hands and feet is limited by what your limbs can do independently. Two practical notes.
The hi-hat foot is the most useful reference. A foot playing a steady two under a hand playing three is the cheapest polyrhythm in drumming, and it is available on any kit. Hi-hat foot control is covered in hi-hat techniques.
A double pedal makes more polyrhythms available because it allows both feet to be independent. See double bass drum technique for the setup, though a polyrhythm is not a speed technique and the pedal helps with independence rather than tempo.
Metronome practice is essential and has to be set carefully. The standard approach — set the click to the common pulse of both layers rather than to either layer — is covered in how to practice with a metronome.
::: callout
The counterintuitive part: polyrhythms are usually described as an advanced technique and most drummers meet their first one in their first month — a triplet fill over a straight kick is a 3:2. What is advanced is not the polyrhythm itself but hearing both layers simultaneously, and that is a perceptual skill rather than a motor one. It is why the stage where the layers separate usually arrives suddenly: the hands did not get faster, the ear changed.

The relation to odd meters
Odd time signatures and polyrhythms are related, and the connection is worth understanding because it saves confusion.
An odd meter is one grouping of an unusual length — a 7/8 bar is seven notes with a shape.
A polyrhythm is two groupings at once within the same time.
Some music that is described as odd-meter is actually a polyrhythm, and the reverse. A 7/8 groove where the bass plays 4+3 while the drums play 2+2+3 is both. Odd time signatures covers the single-grouping method, and it is the prerequisite: a drummer who cannot feel a 2+2+3 will not be able to run another grouping against it.
Where to start, practically
For a drummer who wants to work on this, one exercise is enough for the first month:
Play a 3:2 at 70 BPM for two minutes a day, with the hi-hat foot on the two-side and the hands on the three-side. Then the reverse. Then at 80 BPM. That is it.
No other exercise builds the same thing, and everything else — 4:3, 5:4, the gospel patterns — is a variation on the same process.
::: verdict
Set the metronome to 70 BPM and play a 3:2 for two minutes: hi-hat foot on two, hands on three. Then swap so the hands play two and the foot plays three. If the swap is much harder than the original, you have learned a pattern rather than a relationship — and the relationship is the technique.

Frequently asked questions
The questions readers send us most about polyrhythms drums.
Two different groupings played simultaneously within the same span of time, such as three evenly spaced notes in the time it takes to play two. Both layers restart together at the end of the cycle, which is what makes it a repeating pattern rather than a collision.
3:2 — three against two. Divide the time into six equal parts, with the two-side on parts 1 and 4 and the three-side on parts 1, 3, and 5. It is the foundation of most Latin and African-derived rhythms and the practical starting point for everything else.
Start at 50 BPM and learn the pattern as a sequence of individual events rather than as two simultaneous layers. Then raise the tempo until the ear starts hearing two layers — usually somewhere around 70 to 90 BPM. Then apply it to a groove, because a polyrhythm practised as an exercise has no musical value.
No. An odd time signature is a single grouping of an unusual length, such as 7/8. A polyrhythm is two groupings happening at the same time. Some music is both at once, and odd time signatures are usually the prerequisite to understanding the polyrhythmic version.
3:2 and 2:3 appear constantly, particularly in Latin, gospel, and contemporary church drumming. 4:3 is common in jazz and progressive music. 5:4 and 7:4 are rare outside progressive and modern composition, and most working drummers never need them.
