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 main categories: pitched, which can produce specific notes, and unpitched, which do not have a definite pitch. Percussionists play a vital role in creating rhythm and enhancing the overall sound of the ensemble. They often provide the backbone of the music, setting the tempo and adding texture. The variety of instruments allows for a wide range of sounds, contributing to the dynamic and expressive qualities of a performance.
