The Jap fiddle or Japanese fiddle was a one-stringed bowed instrument used by street performers, music hall performers, and vaudevillians around the start of the 20th century, particularly in the United Kingdom and United States. The instrument was particularly associated with Cockney blackface performer G. H. Chirgwin. A variant was later produced with a vibrating membrane and horn for amplification, as a one-stringed phonofiddle.
