Xylophone
The modern orchestral xylophone developed from xylophones found in Africa and Asia. It came as a folk instrument to countries in Central Europe. It was first used in an orchestra by Humperdinck in his opera Hansel and Gretel. It was also used by Saint-Saëns in his Danse macabre where it is supposed to sound like a skeleton, and in his Carnival of the Animals where it is supposed to sound like fossils.
