(redirected from Cross-rhythm)
Also found in: Dictionary.



(cross rhythm), in music, the simultaneous use of two or more different rhythmic patterns. In general, “polyrhythm” means the combining of any rhythmic patterns. It was the norm for European polyphonic music, beginning with the 12th-century motet. In this general sense, polyrhythm includes the simplest rhythmic combinations (for example, quarter notes in one voice and eighth notes in the other), as well as compound rhythmic combinations, which are defined as polymetry.

In a specialized sense, polyrhythm is the vertical combination of rhythmic patterns characterized by the absence of the smallest unit of time common to all voices (for example, a combination of duplets and triplets, or triplets and quintuplets). This type of polyrhythm is characteristic of works by Chopin, Scriabin, A. Webern, and A. Berg.
