Hear two pulse groups over one shared cycle. Change the ratio, slow it down, mute either stream, and use the visual beat lanes to make cross-rhythms feel playable.
Ready to play 3 against 2.
Three evenly spaced pulses fit over the same time as two. The two streams meet at the start of each cycle.
The tempo controls Pulse A. Both groups always finish together, so increasing Pulse A also shortens the shared cycle.
The most useful starting point. Think “not difficult” or divide the cycle into six equal subdivisions.
A twelve-subdivision grid helps reveal where the pulses separate and meet.
Slow the tempo and learn each hand alone before combining the streams.
A polyrhythm places different numbers of evenly spaced attacks inside the same span of time. The least common multiple of the two pulse counts gives the smallest shared grid that can describe both streams. For 3:2, the shared grid has six subdivisions: the three-pulse stream lands every two subdivisions, and the two-pulse stream lands every three.
The first beat is accented so you can hear the cycle restart. Ratios with a common factor, such as 6:4, reduce to a simpler relationship such as 3:2 and contain repeated alignments inside the displayed cycle.
Read the algorithmic music guide to connect polyrhythm with Euclidean patterns and probability. Use the ear training exercises to strengthen interval, chord, scale, and pitch recognition, or open the chord progression generator when you want to apply a cross-rhythm to a harmonic loop.
