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

At about the same time, a new form of key pressed from beneath was developed. These keys were much more practical for faster music and easier to handle; eventually they completely replaced keys pulled up from above. Medieval depictions of the "symphonia" show both types of keys. During the Renaissance, the hurdy-gurdy was a very popular instrument (along with the bagpipe) and the characteristic form had a short neck and a boxy body with a curved tail
