PROBLEM TO BE SOLVED: To execute retrieval for a music data base at a remote place, and to allow plural retrievers to execute retrieval to the same music data base by setting input terminal equipment at various places or desired objects. SOLUTION: In this music retrieval system, a device for inputting a singing voice and a system for retrieving the music voice are separated so that music retrieval using a network can be executed. Also, at the time of rough matching to be executed for permitting an error included in voice height and voice length obtained from the singing voice, a threshold for validly using the both voice height and voice length information can be decided, and matching can be attained by arbitrarily changing the precision of roughness. Moreover, even when music in the music data base is updated, the optimal threshold can be immediately decided for the updated music data base, and music retrieval whose correctly answering rate is high can be attained by using the voice height and voice length.
