Music box - online puzzles

A music box or musical box 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. They were developed from musical snuff boxes of the 18th century and called carillons à musique (French for "chimes of music "). Some of the more complex boxes also contain a tiny drum and/or bells in addition to the metal comb.
