<P>PROBLEM TO BE SOLVED: To provide a chord name detector which improves the detection accuracy of a chord name detection result. <P>SOLUTION: The chord name detector has: a playing part 70 playing an acoustic signal; the first input part 90 receiving a division of a phrase including a plurality of measures; a phrase similarity detecting part 100, which finds out the number of measures in each phrase from a position of the division of the phrase, checks the similarity thereof by comparing composition sound of a chord name detected from the phrase, having the same number of measures and allocates a unique ID to each phrase having predetermined threshold or more degrees of similarity for representing the similarity thereof; a display part 80 for displaying a similarity detection condition to a user; the second input part 110 for receiving the determination of the similarity detection condition; a phrase similarity defining part 120, which changes the threshold when the determination of the similarity detection condition cannot be defined, and makes the phrase similarity detection part 100 redetect the similarity of each phrase and makes it redetect the similarity so that the same phrase part has the same measure division and the same chord, in response to the definition of the determination; and a correction part 130. <P>COPYRIGHT: (C)2010,JPO&INPIT |
