Hurdy-gurdy Hurdy-gurdy The hurdy-gurdy is a stringed instrument that produces sound by a hand crank-turned, rosined wheel rubbing against the strings. The wheel functions much like a violin bow, and single notes played on the instrument sound similar to those of a violin. Melodies are played on a keyboard that presses "tangents"—small wedges, typically made of wood—against one or more of the strings to change their pitch. Like most other acoustic stringed instruments, it has a sound board and hollow cavity to make the vibration of the strings audible. Most hurdy-gurdies have multiple drone strings, which give a constant pitch accompaniment

These instruments, mostly brass or wind, were built much better than those played by itinerants, and musicians brought them back
