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.Traditionally, the instrument is tuned C-G-C-A and has tangents on the top three playing strings, with the bottom string functioning as a drone. Our nyckelharpas are tuned in fifths (C-G-D-A) and all four strings are keyed. They have a range of three and a half octaves, from C below middle C.
