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
Hurdy-gurdy to keys that change the vibration length of the string, much as a guitarist uses his or her fingers on the fretboard of a guitar. In the earliest hurdy-gurdies these keys were arranged to provide a Pythagorean temperament, but in later instruments the tunings have varied widely, with equal temperament most common because it allows easier blending with other instruments. However, because the tangents can be adjusted to tune individual notes, it is possible to tune hurdy-gurdies to almost any temperament as needed. Most contemporary hurdy-gurdies have 24 keys that cover a range of two chromatic octaves. To achieve proper
