Mallet percussion refers to a family of musical instruments that are played by striking their surfaces with mallets. Common examples include the xylophone, marimba, and vibraphone. These instruments typically consist of wooden or metal bars arranged in a keyboard layout, producing melodic sounds when struck. Mallet percussion instruments are often used in various music genres, including classical, jazz, and contemporary music. They can be found in orchestras, bands, and solo performances, showcasing their versatility and unique tonal qualities. The choice of mallet material, such as rubber or yarn, can also affect the sound produced.
