Percussion instruments are the heartbeat of any band and play not only the rhythm, but the melody and harmony as well. They are defined as any instruments that are played by being struck, shaken, rubbed or scraped.
Most percussion instruments have a distinct tone or pitch and even a set of drums can be tuned. Instruments like the xylophone, bells, and even the piano are struck to produce a sound. Some other common percussion instruments include the snare drum, bass drum, cymbals, triangle, wood block and tambourine.
