MUSICAL DATA RETRIEVAL ON THE BASIS OF RHYTHM PATTERN SIMILARITY

摘要

It is an object of the present invention to provide an improved technique for searching for a tone data set of a phrase constructed in a rhythm pattern that satisfies a predetermined condition of similarity to a rhythm pattern intended by a user. The user inputs a rhythm pattern via a rhythm input device (10). An input rhythm pattern storage section (212) stores the input rhythm pattern into a RAM on the basis of clock signals output from a bar line clock output section (211) and trigger data included in the input rhythm pattern. A rhythm pattern search section (213) searches through a rhythm database (211) for a tone data set presenting the highest degree of similarity to the stored input rhythm pattern. A performance processing section (214) causes a sound output section (26) to audibly output the searched-out tone data set.
