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 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
