Hurdy-gurdy is a drone‑based musical style centered on the hurdy-gurdy (vielle à roue), a string instrument sounded by a rosined wheel turned with a crank. Melodies are played on keyed chanterelle strings while one or more bourdon (drone) strings provide a continuous tonal bed. A distinctive "buzzing" bridge (the trompette or chien) can be engaged rhythmically by subtle wrist accents on the crank, turning the instrument into its own rhythm section.
The genre draws on medieval, Renaissance, and rural European folk dance traditions (especially from central France, Iberia, and Central/Eastern Europe), but it also thrives in contemporary folk revival and experimental settings. Typical repertoire includes bourrées, waltzes, marches, and modal airs in Dorian, Mixolydian, and Aeolian modes, performed solo or with companions such as bagpipes, diatonic accordion, fiddle, and frame drums.
Early forms of the hurdy-gurdy, such as the large two-player organistrum, appear in Romanesque sculpture (notably at Santiago de Compostela). Initially associated with sacred and courtly contexts, the instrument soon evolved into smaller, single-player vielles à roue suitable for itinerant and secular performance.
By the Baroque era, the hurdy-gurdy experienced a fashionable wave in France, entering salons alongside the musette (bagpipe). Composers and aristocratic amateurs embraced pastoral aesthetics while the instrument remained deeply rooted in village dance music—especially bourrées and marches—in regions like Berry, Bourbonnais, and Auvergne.
Industrialization and changing tastes pushed the instrument to the margins, where it survived in regional folk traditions and as a street instrument. Local luthiers preserved techniques, tunings, and repertories, ensuring continuity into the 20th century.
Postwar folk revivals in France, Spain, and Central/Eastern Europe sparked renewed interest. Musicians standardized modern setups (e.g., G/C or D/G systems), revived dance repertoires, and documented regional styles. Innovative players began extending technique and harmony, treating the instrument as both melodic and percussive.
Contemporary artists fuse the hurdy-gurdy with rock, metal, ambient, and experimental music, exploiting drones, modal loops, and the trompette’s groove. Workshops, festivals, and new lutherie have globalized the instrument, making hurdy-gurdy a vibrant bridge between early music, folk dance, and modern sound design.
