The percussion section of an orchestra or band consists of instruments that produce sound by being struck, shaken, or scraped. Common instruments in this section include drums, cymbals, marimbas, and tambourines. Percussion instruments can be classified into two categories: tuned (like xylophones) and untuned (like snare drums). Percussionists play a vital role in music by providing rhythm, texture, and dynamics. They often enhance the overall sound and energy of a performance, contributing to the emotional impact of a piece. The percussion section can vary in size and instrumentation depending on the style of music being performed.
