The hurdy-gurdy is a unique stringed musical instrument that produces sound through a combination of a rotating wheel and strings. It is played by turning a hand-crank, which causes the wheel to rub against the strings, similar to a violin bow. The instrument often features keys that can be pressed to change the pitch of the strings, allowing for melody and harmony. Historically, the hurdy-gurdy has roots in medieval Europe and has been used in various folk music traditions. It is often associated with the music of France, Germany, and Eastern Europe. The instrument's distinctive sound and appearance make it a fascinating addition to both traditional and contemporary music.
