context_page_description: Polyphon is a disc-playing music box, a mechanical device first manufactured by the Polyphon Musikwerke, located in Leipzig, Germany. Invented in 1870, full-scale production started around 1897 and continued into the early 1900s. Polyphons were exported all over world and music was supplied for the English, French and German markets, as well as further afield, with music cataloged for the Russian, Polish and Balkan regions. Polyphon is also a record label as registered by German Polyphon Musikwerke AG in 1908. Polyphon traded under the Polydor label since 1913 with their trademarks Polyphon Musik and Polyphon Record.
context_section_description: Original examples still exist of 1870-invented Polyphon and contemporary manufacturers produce small quantities of both the devices and discs.
caption: A Polyphon is a large disk-operated music box. The plectra protrude from the backside of the disk. As the disk rotates they contact a ratchet mechanism that plucks the tines. A large sounding board amplifies the sound. Many interchangeable disks were be available for producing favorite melodies.
