Encyclopedia: A music box (American English) or musical box (British English) is an automatic musical instrument in a box that produces musical notes by using a set of pins placed on a revolving cylinder or disc to pluck the tuned teeth (or lamellae) of a steel comb. The popular device best known today as a "music box" developed from musical snuff boxes of the 18th century and were originally called carillons à musique (French for "chimes of music"). Some of the more complex musical boxes also contain a tiny drum and/or bells in addition to the metal comb.
