What are the differences between bells and xylophone in terms of sound, construction, and musical applications?

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.
