Describing music or patterns that involve more than one rhythm happening at the same time.
The drummer played a polyrhythmic beat that made the song feel more complex and interesting.
Polyrhythmic → It is formed from "poly-" (from Greek "polus", meaning many) and "rhythmos" (meaning rhythm). The word describes a musical structure that involves many different rhythms played simultaneously.
Think of 'many' ('poly-') rhythms ('rhythmos') working together — that's what polyrhythmic means.
