Analysis section divides waveform data of a given music piece into waveform data of a plurality of fragments and divides the waveform data of each of the fragments into one or more events of sound, and obtains a character value indicative of a character of the waveform data pertaining to each of the divided events. Storage section stores respective music piece data and music piece composing data of one or more music pieces. The music piece composing data include a character value indicative of a character of the waveform data pertaining to each of the events of each of the fragments. Search section searches (or retrieves) for, from among the stored music piece composing data, one event or a plurality of successive events having a character value of a high degree of similarity to one or more events included in a designated fragment.

Fragment search apparatus and method

Storage section has stored therein music piece data sets of a plurality of music pieces, each of the music piece data sets including respective tone data of a plurality of fragments of the music piece and respective character values indicative of musical characters of the fragments. Each of the fragments of a selected main music piece is selected as a main fragment, and each one, other than the selected main fragment, of a plurality of fragments of two or more music pieces is selected as a sub fragment. A similarity index value indicative of a degree of similarity between the character value of the main fragment and the character value of the specified sub fragment is calculated. For each of the main fragments, a sub fragment presenting a similarity index value that satisfies a predetermined selection condition is selected for processing the tone data of the main music piece.
