ABSTRACT:
A method and apparatus for tuning a musical instrument. Measurements are made of the inharmonicities of three notes (e.g., F3, A4 and C6 in a piano). One of the notes (e.g. A4) is a standard note that is to be tuned to a standard frequency. The measured inharmonicities of these notes determine a slope of a tuning curve and a position to intercept the standard note frequency according to the following: ##EQU1## Y(p,N) is the cents deviation relative to the equally tempered scale of partial p of note N, F is a factor by which the inharmonicity increases per octave taken from the measurement, B(N) is the inharmonicity of note N, and B(STD) is the inharmonicity factor of a standard note (e.g., A4 at 440 Hz).
