INHARMONICITY OF NONUNIFORM OVERWOUND STRINGS

In our previous paper [10], the transverse wave equation for the case of a stepped stiff string was described, and the numerical results of the frequency equation were compared with data from experiments on pia no strings. It was evident from these results that the theory presente d there gave a better fit to measured inharmonicities than Fletcher's analysis for a uniform overwound string. In this paper, we describe me asurements of inharmonicity carried out on nonunifom overwound strings mounted on a rigid monochord. The measurements are in good agreement with the theoretical predictions taking account the nonuniformity of t he winding.
