What is music played by a small group of instruments?

Music played by a small group of instruments is often referred to as chamber music. This genre typically involves ensembles ranging from two to about ten musicians, with common formations including string quartets, piano triOS, and wind quintets. Chamber music emphasizes individual expression and interaction among musicians, allowing for a more intimate performance experience compared to larger orchestral works. It often features a diverse repertoire, spanning classical to contemporary compositions.
