cross-rhythm explained
The simultaneous use of two or more conflicting rhythmic patterns that create a complex composite rhythm
In Depth
Cross-rhythm occurs when different parts of an ensemble play patterns that seem to contradict each other's metre. The most common cross-rhythm is 3 against 2 (triplets against duplets), but ratios of 4:3, 5:4, and more complex patterns appear in advanced music. West African drumming traditions are built on cross-rhythmic principles, with multiple interlocking patterns creating a rich rhythmic tapestry. Brahms, Chopin, and many jazz musicians use cross-rhythms to create rhythmic tension and complexity.
The West African bell pattern, a 12-beat cycle that can be grouped as either 3+3+3+3 or 4+4+4, is considered the foundational cross-rhythm underlying much of African and African-diaspora music.
