Stringed instrument performance evaluation apparatus and a stringed instrument played evaluation program

摘要

PROBLEM TO BE SOLVED: To improve evaluation accuracy of a stringed instrument by accurately sampling performance sound thereof.SOLUTION: A stringed instrument performance evaluation device executes: a pitch notation level conversion processing which converts frequency conversion information into a pitch notation level per pitch notation; a weighting processing which weights the pitch notation level divided by octave with a coefficient set for each octave; a pitch notation level integration processing which integrates the weighted pitch notation level for each pitch notation and calculates an integrated level for each pitch notation; a performance pitch notation determination processing which determines the pitch notation having a prescribed integration level as a performance pitch notation; and an evaluation processing which performs evaluation by comparing the performance pitch notation determined by the performance pitch notation determination processing with reference performance information outputted by performance means according to musical performance.
