Abstract
A sharping device for shortening the length of a vibrating string on a lever harp is described. The device consists of an adjustable, freestanding fret in combination with a plastic, rotating blade sharping lever, which the harp player activates by the push of one finger. When rotated, the lever causes a vibrating string to be stopped against the fret. Both lever and fret are located along the neck of a harp so as to raise the frequency of a vibrating string by one semitone.
