The xylophone is a musical instrument consisting of a series of wooden bars arranged in order of pitch. When struck with mallets, the bars produce distinct tones, creating a melodic and resonant sound. It is played by striking the bars with either wooden or rubber mallets, allowing musicians to create beautiful melodies and rhythmic patterns. The xylophone's unique timbre and versatility make it a popular choice in orchestras, bands, and solo performances, adding a vibrant and percussive element to the music.
