PROBLEM TO BE SOLVED: To provide a performance evaluation device capable of diagnosing a performance condition of a user.;SOLUTION: When an attractor obtained by applying Takens plot analysis processing on time series data (key-on interval data L₀-L_n) derived from user performance timing is compared with a basic attractor determining a previously stored performance condition, it is determined that the user performance condition is similar to that of a pianist A or that the user performance condition is rough, for example. In this way, the user performance condition can be evaluated in a similar manner to that of a skilled evaluator, and an advice on exercises in the performance can be given.;COPYRIGHT: (C)2009,JPO&INPIT
