Tree-structured Representation of Melodies for Comparison and Retrieval
David Rizo, Jose Manuel Iñesta · 2002
The success of the Internet has filled the net with lots of symbolic representations of music works. Two kinds of problems arise to the user: the search for information from content and the identification of similar works. Both belong to the pattern recognition domain. In contrast to most of the existing approaches, we pose a non-linear representation of a melody, based on trees that express the metric and rhythm of music in a natural way. This representation provide a number of advantages: more musical significance, more compact representation and others. Here we have worked on the comparison of melodies and patterns, leading to motive extraction and its use for the identification of complete melodies.
