A percussion ensemble is a group of musicians who primarily play percussion instruments, which include drums, cymbals, marimbas, and tambourines. These ensembles can vary in size and often perform a wide range of musical styles, from classical to contemporary. The focus is on rhythm and texture, allowing for creative expression through various techniques and sounds. Percussion ensembles are commonly found in educational settings, such as schools and universities, where they help students develop their rhythmic skills and teamwork. Notable composers, like Steve Reich and John Cage, have written pieces specifically for percussion ensembles, showcasing the versatility and richness of these instruments.
