Hardanger fiddle

A hardanger fiddle (Norwegian: hardingfele) is a traditional stringed instrument considered the national instrument of Norway. In modern designs, this type of fiddle is very similar to the violin, though with eight or nine strings (rather than four as on a standard violin) and thinner wood. The earliest known example of the hardingfele is from 1651, made by Ole Jonsen Jaastad in Hardanger, Norway. Originally, the instrument had a rounder, narrower body. Around the year 1850, the modern layout with a body much like the violin became the norm. The F-holes of the hardanger fiddle are distinctive, oftentimes with a more "sunken" appearance, and generally straighter edges (unlike the frilly, swirly F-holes of a violin). Four of the strings are strung and played like a violin, while the rest, named understrings or sympathetic strings, resonate under the influence of the other four. These additional strings are tuned and secured with extra pegs at the top of the scroll, effectively doubling the length of a Hardingfele scroll when compared to a violin. The sympathetic strings, once fastened to their pegs, are funneled through a "hollow" constructed fingerboard, which is built differently than a violin's, being slightly higher and thicker to allow for these extra strings. The resonant strings lie on the center of the special bridge, attached to extra hooks (or fine-tuners) on the tailpiece. Carved out within the center of the bridge is a smaller secondary "bridge", or opening, designed specifically for these resonant strings to pass through. This is where the resonance is picked up and reverberated. As notes are played, the vibrations are sent through the bridge, where the sympathetics echo those notes. The hardingfele's bridge is unique compared to other bowed instruments. It is somewhat taller and wider, resulting in the strings being slightly lower and further...
