A musical box (UK usage; music box in US English) is a 19th century automatic musical instrument that prouces sounds by the use of a set of pins placed on a revolving cylinder or disc so as to strike the tuned teeth of a steel comb. They were developed from musical snuff boxes of the 18th century and called carillons à musique. Some of the more complex boxes also have a tiny drum and small bells, in addition to the metal comb. Alec Templeton, an avid collector of music boxes and a professional concert musician, once noted that the tone of a musical box is unlike that of any musical instrument (although it is best described as somewhere between the timbres of an mbira).
