Polyrhythm

Polyrhythm is a rhythmic technique where two or more different rhythms are played simultaneously, each with its own grouping of beats. For example, a 3 against 2 (3:2) polyrhythm means three evenly spaced notes played in the time of two. Each rhythm maintains its own pulse, creating a complex and often hypnotic texture. Polyrhythms are widely used in African music, jazz, contemporary classical, and some forms of experimental electronic music.
