Mechanical music boxes are small devices that produce music through a series of metal tines or pins. When a winding key is turned, a cylinder or disc rotates, striking the tines to create melodies. These boxes often feature intricate designs and can be made from various materials, including wood and metal. The history of mechanical music boxes dates back to the late 18th century, with early examples originating in Switzerland. They became popular as decorative items and gifts, often playing well-known tunes. Today, collectors appreciate both their craftsmanship and the nostalgic music they produce.
