Today, the Hardanger violin is regarded as Norway's national instrument. The name comes from the fact that the first known instruments were made in the Hardanger area.The modern Hardanger violin is a little smaller than the ordinary violin, richly decorated with pen drawings and mother-of-pearl inlays, and usually has 4 or5 resonating understrings.
Except for the element of understrings, where the Hardanger violin has relatives in both the near and far East and in Europe, the Hardanger vioin is today an exclusively Norwegian phenomenon.The oldest Hardanger violin that has been found and registered is dated 1651(the Jastad violin).
E,Grieg composed many famous music based on the melancholic tone of this instrument.
