Tuned percussion refers to musical instruments that produce specific pitches when struck. These instruments are designed to resonate at particular frequencies, allowing them to create melodies and harmonies. Common examples include the xylophone, marimba, and vibraphone, each featuring bars or keys that are tuned to different notes. Unlike untuned percussion instruments, such as the snare drum or cymbals, which produce a more indefinite pitch, tuned percussion can be used in both solo and ensemble settings. They are often featured in orchestras and bands, contributing to the overall texture and richness of the music.
