Layering pulses
Three against two: a step-by-step way to feel it
Written by a guitar teacher who runs a private studio in Japan. Published September 18, 2026
Three against two is the polyrhythm you meet first: three even notes in one hand while the other plays two, in the same span of time. It turns up in ballads, in Latin music, in almost any arrangement that wants the beat to feel wider than it is. It is also the gateway — once you can switch between the two pulses at will, four against three and five against four are the same skill at a finer grain.
What is actually happening
Divide one bar into six equal parts. The “two” pulse lands on parts 1 and 4. The “three” pulse lands on parts 1, 3 and 5. They meet only at the start of the cycle, and the remaining notes alternate. Counting six and dropping the parts you do not need is the arithmetic behind every method of learning this.
A circular dial shows this better than a line does, because the cycle closes: the two rings meet at the top and drift apart in a pattern you can watch repeat.
Five steps
- Hear the grid first. Set one track to six even notes per bar at a slow tempo — around 50 BPM is enough. Listen until the six feels flat and even, with no accent implied.
- Add the two. On a second track with a different sound, play the pulse that lands on the first and fourth of those six. You now hear both, and the relationship is already correct.
- Add the three. On a third track, play the pulse that lands on the first, third and fifth. Listen to the whole thing for a minute without playing anything yourself.
- Mute the grid. Turn off the six. What remains is the polyrhythm alone. This is the sound you are aiming for, and most people find it recognizable immediately — it is the rhythm of the phrase “not dif-fi-cult” said evenly.
- Take one side over. Mute the three and play it yourself against the remaining two, then swap. Playing the side you find harder while hearing the other is the whole exercise.

Set the beats per bar to two, then give one track a division of two and another a division of three. Each track has its own sound, so make them clearly different — a high click against a low one. Mute and solo let you do steps four and five without rebuilding anything.
Common traps
- Speeding up to hide it. At a fast tempo a sloppy three against two sounds like a swung triplet and passes unnoticed. Practice it slowly enough that every note has to be placed deliberately.
- Learning it as a word and stopping there. Mnemonics get you the sound quickly, but they tie it to one tempo. Once the phrase works, go back to the grid and rebuild it at three or four different tempos.
- Only ever playing the three. Most people practice the faster side because it feels like the active one. The harder skill is holding the slow side steady while the fast side runs.
Where to go next
Four against three uses a grid of twelve and follows exactly the same five steps. The reason it feels harder is not the arithmetic but the gaps: the two pulses coincide once per cycle and never sit close enough to check yourself in between. If you can build it from the grid and take the grid away, you have the method for every polyrhythm you will meet.
