Hardingfele refers to the Hardanger fiddle tradition of Norway—both the specially built fiddle and its repertoire of rural dance-tunes (slåttar) and listening pieces.
The instrument looks similar to a violin but has 4 (sometimes 5) bowed strings above, plus 4–6 sympathetic strings underneath that vibrate in resonance, producing a shimmering, bell-like halo. Players use cross-tunings (scordatura) tailored to each tune family, abundant double-stops and drones, highly ornamented fingering, and subtle bow pulses. Rhythms often carry the distinctive asymmetrical triple-time swing of regional springar styles, and melodies gravitate to modal colors (Dorian, Mixolydian) with flexible intonation.
The Hardanger fiddle emerged in western Norway (Hardanger/Voss) in the 1600s, likely shaped by Baroque violin-making ideas and local folk aesthetics. By the 1700s, it had spread to Telemark, Setesdal, Valdres, and other valleys, where distinctive regional repertoires and tunings formed around dance-types (springar, gangar, halling) and ceremonial pieces (e.g., brureslått—wedding tunes).
A "golden age" of local virtuosi and makers established the instrument’s prestige. Legendary fiddlers like Myllarguten (Torgeir Augundsson) brought valley styles to national attention, including a landmark 1849 concert facilitated by violinist-composer Ole Bull, which helped bridge folk and art-music spheres. Families of luthiers (notably in Hardanger and Telemark) refined the decorated, inlaid instrument with sympathetic strings that define its sound.
Modernization and urbanization reduced rural dance contexts, but community ensembles (spelemannslag), archives, and competitions like Landskappleiken safeguarded styles. Collectors and scholars documented regional variants, bowing language, microtiming (the "swing" of springar), and tunings. From mid-century onward, a broader folk revival brought the hardingfele to stages, radio, and recordings.
Today, tradition-bearers and innovators coexist. Masters maintain local dialects of style, while contemporary artists integrate hardingfele with jazz, ambient, and even metal and pop textures. Education, festivals, and a living network of makers and players sustain the instrument at the heart of Norway’s musical identity.
