Cross-Rhythm — How to Count, Play & Practice
A cross-rhythm is a specific type of polyrhythm where a rhythmic pattern in one voice systematically conflicts with the prevailing meter, creating an interlocking effect. Unlike a brief polyrhythmic passage, cross-rhythms are sustained patterns that layer contrasting groupings throughout a section or entire piece. They are central to West African drumming traditions and permeate jazz, Afro-Cuban, and contemporary music.
How to Count
Maintain the main meter with your foot or one hand while playing the cross-rhythm with another. For a 3-over-4 cross-rhythm, keep a steady four-beat pulse with your foot and play three evenly spaced notes across four beats with your hand. Use a metronome on the main pulse and place the cross-rhythm notes at mathematically even intervals within each cycle.
Common Mistakes
- Gravitating toward the cross-rhythm and losing the underlying meter, which defeats the purpose of the rhythmic tension.
- Playing the cross-rhythm as an approximation rather than with precise mathematical placement.
- Treating cross-rhythms as decorative rather than structural — in many traditions they form the fundamental rhythmic fabric.
Practice Exercise
Practice a 3-over-4 cross-rhythm: set a metronome to 60 BPM (four beats per cycle). Tap your right hand three evenly spaced times across four beats — at beats 1, 2.33, and 3.67. Start by using a 12-unit subdivision (tap at subdivisions 1, 5, and 9 out of 12). Practice the right hand alone, then add the left hand on all four beats.
Suggested metronome tempos: Slow: 40 BPM · Medium: 60 BPM · Fast: 90 BPM

FAQ
What is the difference between a cross-rhythm and a polyrhythm?
All cross-rhythms are polyrhythms, but not all polyrhythms are cross-rhythms. A polyrhythm is any layering of different rhythmic patterns. A cross-rhythm specifically refers to a sustained, systematic conflict between a rhythmic pattern and the prevailing meter, creating an interlocking texture.
Why are cross-rhythms important in African music?
Cross-rhythms are foundational in West African and Afro-Cuban music, where multiple interlocking patterns create a rich rhythmic tapestry. Rather than being decorative, they form the structural basis of the music, with each voice contributing an essential part of the composite rhythm.
