Hurdy-gurdy strings are purely generated electronically by the keys and also in combination with the rotation of the wheel. The signals for drone strings and the snares are generated by the crank movements of the wheel. The data exchange of the musical information between the hurdy-gurdy and connected computers, samplers or synthesizers are managed via MIDI interface. 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
Hurdy-gurdy sensitivity of the buzzing bridge can be altered by turning a peg called a "tirant" in the tailpiece of the instrument that is connected by a wire or thread to the "trompette". The "tirant" adjusts the lateral pressure on the "trompette" and thereby sets the sensitivity of the buzzing bridge to changes in wheel velocity. When hard to trigger, the strike or the bridge is said "sec" (dry), "chien sec" or "coup sec". When easy to trigger, the strike or the bridge is said "gras" (fat), "chien gras", or "coup gras". There are various stylistic techniques that are used as
