PROBLEM TO BE SOLVED: To improve evaluation accuracy of performance sound of a stringed instrument and evaluate it based on acoustic feeling.SOLUTION: A stringed instrument performance evaluation device executes: a reference performance information reading processing which reads out reference performance information in synchronism with performance of music information; a level correction processing which performs a first level correction for each pitch notation level sampled by a performance pitch notation sampling processing against the pitch notation level of the correct pitch notation corresponding to the reference performance information read out, and which performs a second level correction for each pitch notation level against the pitch notation level of the incorrect pitch notation not included in the reference performance information; and an evaluation processing which evaluates the performance sound information on the basis of the level-corrected pitch notation level. |
