Melody‐based retrieval of music

Nowadays, available music information is increasing rapidly from fast growing digital libraries and the Internet. How to effectively retrieve music data is a challenging task and content‐based retrieval of music is a relatively large area. Much work that aims at creating acoustical waveforms of music has been carried out. But to many people, the most important and useful feature of music is the melody. This paper focuses on the melody‐based retrieval of music, which can be regarded as a kind of content‐based retrieval of music but much closer to the actual nature of music. It can be divided into three parts for studying: the extraction of melodic attributes, the melody input methods and the matching methods.
