Music search system and music search apparatus

Abstract

A time-series signal input section 205 inputs a time-series signal whose on state and off state are repeated alternately. A similar rhythm search section 206 searches a plurality of pieces of rhythm data stored in a data storage section for rhythm data having the same fluctuation pattern as or a similar fluctuation pattern to the time-series signal input to the time-series signal input section 205 . A music-associated information storage section 204 stores music-associated information associated with the piece of music corresponding to the rhythm data in association with the rhythm data. A search result generation section 207 generates the search result using the music-associated information (information of title, etc.,) stored in association with the found rhythm data and outputs the search result through a search result output section 208.

1 .- 19 . (canceled) 
   
   
       20 . A computer-readable program product for causing a computer system to execute procedures for searching a music, 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.   
   
   
       21 . A computer-readable program product for causing a computer system to execute procedures for searching a music, 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 found by the search;   outputting the read music-associated information as the search result of the search;   calculating excess or deficiency of input time of the time-series signal; and   outputting the calculated excess or deficiency.   
   
   
       22 . A computer-readable program product according to  claim 20 , wherein the outputting includes outputting the rhythm data found by the searching in addition to the music-associated information as a search result of the searching; and
 wherein the procedures for searching a music further include storing the rhythm data found by the searching.   
   
   
       23 . A computer-readable program product according to  claim 20 , wherein the storing includes storing at least one item of music data of syllable names, score, words, and music data as the information associated with music, and
 wherein the outputting includes outputting the information associated with music as a part of a search result of the searching.
