Hurdy-gurdy

[Jessica]

A stringled instrument, lutelike in shape, in which
the sound is produced by the friction of a wheel turned by a crank at
the end, instead of by a bow, two of the strings being tuned as drones,
while two or more, tuned in unison, are modulated by keys.

[Sarah]

a musical instrument that is played by turning a handle, causing a small wheel to be rubbed against a set of strings
