Hurdy Gurdy

The hurdy gurdy (also known as a wheel fiddle) is a stringed musical instrument in which the strings are sounded as they pass over a rosined wheel. This wheel, turned with a crank, functions much like a violin bow, making the instrument essentially a mechanical violin. Melodies are played on a keyboard that presses tangents (small wedges, usually made of wood) against one or more of these strings to change their pitch. Like most other acoustic string instruments, it has a soundboard to make the vibration of the strings audible.
