. . "A nyckelharpa (\"keyed fiddle\", or literally \"key harp\", plural nyckelharpor) is a traditional Swedish musical instrument. It is a string instrument or chordophone. Its keys are attached to tangents which, when a key is depressed, serve as frets to change the pitch of the string.The nyckelharpa is similar in appearance to a fiddle or the big Sorb geige or viol. Structurally, it is more closely related to the hurdy-gurdy, both employing key-actuated tangents to change the pitch."@en .
