ABSTRACT:
An improved stationary nut for a harp, for adjusting the position of a harp string relative to sharpening pins of an action plate, includes: an annular collar defining a central bore and, on its outer surface, a generally circumferential groove sized and adapted to be engaged by the harp string, and an elongated shaft sized and adapted to extend through the central bore for fastening the annular collar to the harp. The relative axes of the elongated shaft and the generally circumferential groove defined about the collar are different, and relative rotation between the collar and the shaft is effective to change the radial distance of a segment of the groove surface supporting the harp string from the axis of the shaft in a manner to change the position of the string relative to the sharpening pins, whereby the harp string may be centered on the action plate, between the sharpening pins, for improved playing tone. A harp employing the improved stationary nut is also described.
