3. Rhythm Cyclic patterns Use of accents on particular beats Polyrhythms (rhythms are layered on top of each other) Some rhythms don’t fit together properly, creating tension Syncopated effect, when the accents don’t fall on the strong beats ostinatos - All the drums repeat the same rhythms all the way Small gaps in the rhythms near then end, as performers signal to each other.
