Using the MPEG-7 Standard for the Description of Musical Content

The aim of this paper is discussing possible ways of describing some music constructs in a dual context: that of a specific software application (a tool for content-based management and edition of samples and short audio phrases), and that of the current standard for multimedia content description (MPEG-7). Different musical layers, melodic, rhythmic and instrumental, are examined in terms of usable descriptors and description schemes. After discussing some MPEG-7 limitations regarding those specific layers (and given the needs of a specific application context), some proposals for overcoming them are presented.
