In classic jazz, one almost immediately thinks of the distinctive rhythm of the hi-hats or the ride cymbal when the word-swing is spoken. In more recent popular-music culture, it is almost impossible to name three or four rock, hip-hop, rap, funk or even soul charts or songs that do not have some sort of percussive beat keeping the tune in time. Because of the diversity of percussive instruments, it is not uncommon to find large musical ensembles composed entirely of percussion. Rhythm, melody, and harmony are all represented in these ensembles.

The Hornbostel–Sachs system has no high-level section for percussion. Most percussion instruments as the term is normally understood are classified as idiophones and membranophones. However the term percussion is instead used at lower-levels of the Hornbostel–Sachs hierarchy, including to identify instruments struck with either a non
