Apparatus for searching performance data using a query indicating a tone generation pattern, a method and a recording medium

摘要

A user inputs, as a query pattern, a desired search-object rhythm pattern by operating a rhythm input device (10). At that time, a determination is made of a style of operation performed by a user on a rhythm input device (10), such as whether the user has operated a single key or a plurality of keys, or duration or intensity of the operation, and then, a user-intended performance part is identified, on the basis of the determined style of operation, from among one or more performance parts constituting a performance data set (automatic accompaniment data set). For the thus-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 the input rhythm pattern (query pattern).
