Abstract
A World Wide Web-based melody retrieval system takes a sung melody as a query and retrieves the song's title or other information from a music database over a WWW network which comprises a method of obtaining search clues with the maximum quantity of information from pitch and span (dynamic threshold determination) and a method of effectively reducing the number of answer candidates (coarse-to-fine matching), thus increasing the matching accuracy, and it is characterized in that a user can retrieve music or media with music by singing.
