• This paper describes the phenomenon called the inharmonicity for a struck string. It is known that its spectral components consist of two inharmonic peak series : 'first partials' whose generation mechanism is manifested and 'second partials'. Experimental tests for examining the mechanism of second partials were performed with a model of piano string. The experiments suggest that second partials are those that have frequencies equal to the sum of two normal first partials. Further numerical simulations were done by nonlinear wave equation involving large deflection of string.
