“Harmonic curve” is a mathematical term describing a parabola, or a U-shaped curve formed by the intersection of a plane and a cone. Musically, it is the term for the shape of a harp’s neck (the piece across the top). A curve is necessary so the harp’s strings can change in length rapidly as the notes get higher. The exact shape of this piece varies depending on the luthier (harpmaker). On both pedal and lever harps, the harmonic curve will resemble the design depicted on these wristwarmers. A pattern for the coordinating “Harmonic Curves Tam“ is available separately.
