This invention is directed towards a method of reducing longitudinal modes in vibrating strings of musical instruments having a plurality of strings of fixed lengths, such as pianos and harpsichords. The strings of musical instruments vibrate primarily in transverse modes, but longitudinal modes that are often inharmonious with the transverse modes can also be excited. The method of the present invention identifies those parameters of string vibration that excite longitudinal modes, and minimizes them by avoiding those combinations of parameters that excite them, including transverse frequency modes, longitudinal wave velocity, string length, and placement of the string-exciting device.
