Abstract
A wound musical string includes a core wire and a wrapped wire covering about the core wire. End turns of the wrapped wire covering are coextensive portions of transition sections of the core wire. The transition sections have equilateral triangular, square or other cross sections such that the cross section exhibits equal principal moments of inertia. Consequently the inharmonicity of the string about two axes will be the same and the string will not produce false beats.
