The nyckelharpa is a Swedish keyed fiddle. It has four playing strings and twelve sympathetic strings. Each sympathetic string is tuned to a different chromatic note making the instrument extremely resonant in every key. Tangents attached to keys are pressed against the playing strings to change the pitch. Stopping the strings with tangents combined with the sympathetic strings creates an extremely pure and ethereal sound. This nyckelharpa is tuned in fifths (C-G-D-A) and all four strings are keyed. It has a range of three and a half octaves, from C below middle C.
