Percussion refers to a category of musical instruments that produce sound when struck, shaken, or scraped. Common examples include drums, tambourines, and maracas. These instruments can be made from various materials, such as wood, metal, or plastic, and are often used in different music genres, including jazz, rock, and classical. In addition to traditional instruments, percussion can also include body percussion, where sounds are made using parts of the body, like clapping or stomping. Percussion plays a crucial role in keeping rhythm and adding texture to music, making it an essential element in many musical compositions.
