Abstract

A music search system easily operable by a user to search for a musical piece with accuracy, a method for operating the system, and a recording medium for use with the system. A plurality of music search factors can be successively input to the system, and one or more candidate pieces are presented based on effective inputs in the input music search factors. A user can efficiently supply the system with various sorts of music search information, and can obtain an optimal search result by using a search method particularly suitable for search by each sort of information. Input score information is reproduced according to the input operation, so that the user can immediately confirm most ambiguous score information when using the score information as search information, thereby reducing the probability of the system making an unnecessary search. A presentation form in which a candidate piece is displayed can be selected from a plurality of forms, thereby enabling the user to recognize candidate pieces in various forms, from which the user will select necessary one by various methods. Thus, the user can select any musical piece in an optimal way according to his or her preference. The degrees of matching of a plurality of candidate pieces to each of musical piece search factors are evaluated and information relating to the evaluation results is simultaneously displayed, thereby suggesting, to a user, musical pieces from which one searched for by the user is probable to be found. Also, the system is substantially free from selecting failure.

Claims

1. A system for searching one or more music data from a database, the system comprising:

an input device which inputs at least one search factor; and

a processor which searches one or more music data from a database using the inputted search factor, evaluates a matching degree of each of the searched music data, and displays information representing each of the searched music data on a display in order of a ranking of the matching degree of each of the searched music data.

2. A system according to claim 1, wherein one of the search factors is a melody of the desired music.

3. A system according to claim 1, wherein the processor displays information representing each inputted search factor on the display together with the information representing each of the searched music data.

4. A system according to claim 2, wherein said presentation means ranks the plurality of candidate pieces according to the degrees of matching, and displays the candidate pieces together with ranks determined by said ranking.

5. A system according to claim 1, wherein the processor displays detailed information about one of the searched music data selected by user.

6. A method of searching one or more music data from a database, the method comprising the steps of:

searching one or more music data from a database using at least one search factor;

evaluating a matching degree of each of the searched music data; and

displaying information representing each of the searched music data on a display in order of a ranking of the matching degree of each of the searched music data.

7. A method according to claim 6, wherein one of the search factors is a melody of the desired music.

8. A method according to claim 6, wherein the displaying step includes displaying information representing each inputted search factor on the display together with the information representing each of the searched music data.

9. A method according to claim 6, wherein the displaying step includes displaying detailed information about one of the searched music data selected by user.

10. A medium storing a program which performs a method of searching one or more music data from a database, the method comprising the steps of:

searching one or more music data from a database using at least one search factor;

evaluating a matching degree of each of the searched music data; and

displaying information representing each of the searched music data on a display in order of a ranking of the matching degree of each of the searched music data.

11. A medium according to claim 10, wherein one of the search factors is a melody of the desired music.

12. A medium according to claim 10, wherein the displaying step includes displaying information representing each inputted search factor on the display together with the information representing each of the searched music data.

13. A medium according to claim 10, wherein the displaying step includes displaying detailed information about one of the searched music data selected by user.
