A user inputs, as a query pattern, a desired search-object rhythm pattern using a control, corresponding to a desired one of a plurality of performance parts constituting a performance data set (automatic accompaniment data set), in a rhythm input device (10). An input rhythm pattern storage section (212) stores the input rhythm pattern (query pattern) into a RAM on the basis of a clock signal output from a bar line clock output section (211) and input trigger data. A part identification section (213) identifies a search-object performance part corresponding to the user-operated control. For the identified performance part, a rhythm pattern search section (214) searches an automatic accompaniment database (221) for an automatic accompaniment data set including a rhythm pattern that matches, i.e. has the highest similarity to, the input rhythm pattern (query pattern). |
