State-of-the-art MIR issues are presented and discussed both from the symbolic and audio points of view.
As for the symbolic aspects, different approaches are presented in order to provide an overview of the
different available solutions for particular MIR tasks. This section ends with an overview of MX, the
IEEE standard XML language specifically designed to support interchange between musical notation,
performance, analysis, and retrieval applications. As for the audio level, first we focus on blind tasks
like beat and tempo tracking, pitch tracking, and automatic recognition of musical instruments. Then we
present algorithms that work both on compressed and uncompressed data. We analyze the relationships
between MIR and feature extraction presenting examples of possible applications. Finally we focus on
automatic music synchronization and we introduce a new audio player that supports the MX logic layer
and allows users to play both score and audio coherently.

oped up to now are introduced and analyzed.
Three main approaches are discussed: functional,
reductionistic, and structural. They all provide
solutions for particular MIR situations and they
are synergic to retrieval purposes.
We stress on the importance of identifying
formal models in order to take into account the
This chapter deals with the state of the art of
tools for music information retrieval (MIR) and
playing.
First we focus on the symbolic level of music:
