Euclidean Rhythms Generator

Explore Euclidean rhythms online with presets for tresillo, cinquillo, bossa nova, and bell patterns, plus playback, rotation, share links, and MIDI export.

What this tool includes

Evenly spaced pulses

Distribute hits across steps with the Bjorklund algorithm, then rotate the pattern until the groove sits where you want it.

Recognisable grooves

Start with tresillo, cinquillo, bossa nova, bell, and other patterns that connect the maths to real musical practice.

Playable exports

Hear the pattern in the browser, set the tempo, and export or share the result when it is ready for a session.

Practice tips

Start with a familiar preset before changing steps, pulses, or rotation.
Layer a simple Euclidean pattern with a steady pulse so the spacing becomes musical rather than merely visual.
Use Hand Jam when you want to turn a finished rhythm into a two-handed chord, melody, beat, and synth performance.
