Polyrhythms are one of those things that look intimidating on paper but start making physical sense very quickly once you get your hands — or rather your lap — involved. This exercise doesn’t require reading or notation, just two hands, a surface, and a willingness to feel something that’s genuinely unfamiliar at first.
What you’ll get out of this lesson: You’ll practise subdivisions with the left hand providing a steady quarter-note pulse while the right works through eighth notes, triplets, and sixteenth notes — then move on to polyrhythms, beginning with 3 over 2 and extending to 5 over 2. These patterns translate directly into rhythmic vocabulary for improvisation and composition.
Establishing the pulse and subdivisions
Start by establishing a consistent quarter-note pulse with the left hand. Then take the right hand through every subdivision of that pulse — quarter notes together, then eighth notes, then triplets, then sixteenth notes — and back down again. This is gear-changing from the previous lesson, but now you’re doing it with your hands on your lap rather than counting or vocalising. The physical sensation of each subdivision is important and worth developing separately.
3 over 2 — the first polyrhythm
The left hand plays two beats in the same time that the right hand plays three. This is the most fundamental polyrhythm and the one to get completely solid before moving on. It will feel awkward at first. Stay with it. Once you can feel the relationship between the two cycles rather than counting it out intellectually, you’ve genuinely got it. This one pays dividends — it shows up constantly in music and improvisation.
Don’t overlook the basics, just getting 3 over 2 solid will pay dividends.
5 over 2 and further patterns
Once 3 over 2 is solid, try 5 over 2 — the left hand plays two beats while the right plays five. This is considerably more complex. Another good pattern to work out is 4 over 3. There are methods for working these out mathematically, but the recommendation here is to feel around for them first, record yourself, and then check how you did. The process of finding the pattern is part of the learning.
The musical payoff
Practising these patterns over music — a backing track or even a song playing in the room — adds another layer of challenge and makes the rhythmic ideas directly transferable. Over time, this kind of polyrhythmic awareness leads to genuinely unique compositional ideas and improvisational vocabulary that most players simply don’t have access to. And the side effect is that even simple rhythms feel much more solid once you’ve spent time in more complex territory.
Taking it further: Once 3 over 2 and 5 over 2 feel manageable, try inventing your own combinations — 4 over 3, 5 over 3, 7 over 4. Some of them will produce surprisingly simple patterns; others will be nearly impossible. Try to work the near-impossible ones out rather than giving up — that’s where the real dexterity gains are.
Your homework: Spend five minutes every day this week working on 3 over 2 — left hand keeping a steady two-beat cycle, right hand playing three evenly spaced beats in the same time. Record yourself once during the week and listen back to check whether the two cycles are genuinely independent. Once 3 over 2 feels natural, have a single attempt at 5 over 2 at the end of each session.
