Music information analysis and retrieval techniques

This paper presents the main issues related to music
information retrieval (MIR) domain. MIR is a multi-discipline area. Within this
domain, there exists a variety of approaches to musical instrument recognition,
musical phrase classification, melody classification (e.g. query-by-humming
systems), rhythm retrieval, high-level-based music retrieval such as looking for
emotions in music or differences in expressiveness, music search based on
listeners' preferences, etc. The key-issue lies, however, in the
parameterization of a musical event. In this paper some aspects related to MIR
are shortly reviewed in the context of possible and current applications to this
domain.
