Xylophones
i think all xylophones are the same
Orchestras normally have 1 xylophone or no xylophones at all.
Of course not i mean xylophones from back then were made out of wood. But now they are made out of iron.
Metal xylophones use metal or rubber mallets. Wooden xylophones use metal mallets due to there slower vibrations. The metal mallets help increase its vibrations and make it sound as bright crisp as metal xylophones.
Bells produce a sustained, ringing sound, while xylophones have a more percussive, sharp sound. Bells are typically made of metal and xylophones are made of wood or synthetic materials. Bells are often used in orchestral music for their clear, resonant tones, while xylophones are commonly used in marching bands and jazz music for their rhythmic and melodic capabilities.
