This paper describes the phenomenon called the inharmonicity for a plucked string. Its spectral components consist of two inharmonic peak series: 'first partials' due to the elastic stiffness of a string and 'second partials'. Experimental tests for examining the mechanism of second partials were performed with a monochord string. As in the case of a struck 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.
