Music search system and music search apparatus

A music search method comprising:

• inputting a time-series signal represented by on/off signals;
• storing a plurality of pieces of rhythm data in association with music-associated information associated with music corresponding to the rhythm data;
• searching the plurality of pieces of rhythm data for rhythm data having the same fluctuation pattern as or a similar fluctuation pattern to the time-series signal;
• reading the music-associated information stored in association with the rhythm data found by the searching;
• outputting the read music-associated information as the search result of the search;
• determining whether or not rhythm data of a predetermined similarity degree or more has been found as the result of the searching;
• and
• displaying the search result when rhythm data of the predetermined similarity degree or more has been found as the result of the determining, and displaying the search result when rhythm data of the predetermined similarity degree or more has not been found as the result of the determining.
