Percussion instruments are musical devices that produce sound when struck, shaken, or scraped. They are one of the oldest types of instruments and include a wide variety of forms, such as drums, tambourines, and maracas. These instruments can be classified into two main categories: tuned percussion, which includes instruments like xylophones and marimbas that produce specific pitches, and untuned percussion, which includes instruments like snare drums and cymbals that do not have a definite pitch. Percussion instruments play a crucial role in many musical genres, providing rhythm and enhancing the overall sound. They are commonly used in orchestras, bands, and various cultural music traditions around the world. Famous percussionists, such as Buddy Rich and Tito Puente, have showcased the versatility and importance of these instruments in music.
