polyrhythm means: N. 1. Music that features two separate pulses at different speeds competing within the same music section. A quarter note triplet is an example of a simple polyrhythm that has 3 notes betas in 44 meters. It’s a time- and space-efficient way to describe a tritonet. This is not to be confused with the hemiola. (in Community Dictionary, added by Kali Horn)
