Euclidean Rhythms: Bjorklund Patterns for Musicians
Learn how Euclidean rhythms distribute hits across steps, hear common patterns such as tresillo and cinquillo, and open the free online rhythm generator.
A Euclidean rhythm spreads a chosen number of hits as evenly as possible across a fixed number of steps. Use the generator to hear Bjorklund patterns, rotate the starting point, change tempo, copy the pattern, and export MIDI for a DAW or sequencer.
What this Euclidean rhythm generator does
Steps, pulses, and rotation
Set the grid size, choose how many hits it contains, and rotate the pattern until the accent lands where the music needs it.
Common pattern presets
Start with tresillo, cinquillo, bossa nova, and bell-pattern examples before making custom rhythms.
Audio and visual feedback
Hear the grid and pulse clicks while the circular and linear displays show exactly where each hit falls.
Share and export
Copy a pattern string, share an exact URL, or export MIDI for composition, teaching, or practice.
How to use the Euclidean rhythm generator
- Choose a preset or set the number of steps in the bar.
- Set pulses to decide how many hits should be spread across those steps.
- Use rotation to move the groove against the downbeat without changing the spacing.
- Press play, adjust BPM, then copy the pattern or export MIDI when it fits the part.
Common Euclidean rhythm patterns
- E(3,8) tresillo: three hits over eight steps, often heard as a 3-3-2 rhythm.
- E(5,8) cinquillo: five hits over eight steps with a rolling Afro-Cuban feel.
- E(5,16) bossa pattern: a useful starting point for syncopated guitar, percussion, and sequenced parts.
- E(7,12) bell pattern: seven hits over twelve steps for 12/8 bell and percussion ideas.
