Percussion instruments may play not only [[rhythm]], but also [[melody]] and [[harmony]].{{citation needed|date=May 2024}}

Percussion is commonly referred to as "the backbone" or "the heartbeat" of a [[musical ensemble]], often working in close collaboration with bass instruments, when present. In jazz and other popular music ensembles, the pianist, bassist, drummer and sometimes the guitarist are referred to as the [[rhythm section]]. Most classical pieces written for full orchestra since the time of [[Joseph Haydn|Haydn]] and [[Wolfgang Amadeus Mozart|Mozart]] are orchestrated to place emphasis on the [[String instrument|strings]], [[Woodwind instrument|woodwinds]], and [[Brass instrument|brass]]. However, often at least one pair of [[timpani]] is included, though they rarely play continuously. Rather, they serve to provide additional accents when needed. In the 18th and 19th centuries, other percussion instruments (like the [[Triangle (musical instrument)|triangle]] or [[cymbal]]s) have been used, again generally sparingly. The use of percussion instruments became more frequent in the 20th century classical music.

In almost every style of music, percussion plays a pivotal role.<ref>{{Cite web|url=https://www.elephantdrums.co.uk/blog/guides-and-resources/drums-from-around-the-world/|title=Drums from around the World • Elephant Drums|date=2019-03-13|website=Elephant Drums|access-date=2019-03-13}}</ref> In military [[marching band]]s and [[pipes and drums]], it is the beat of the bass drum that keeps the soldiers in step and at a regular speed, and it is the snare that provides that crisp, decisive air to the tune of a regiment. In classic jazz, one almost immediately thinks of the distinctive rhythm of the [[Hi-hat (instrument)|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.
