This paper deals with a software application to visualize score analysis. Such a tool allows both the enjoyment of music in general, thanks to the synchronized execution of heterogeneous multimedia objects, and the highlighting of the results of score analyses. As a consequence, the user can investigate the compositional process and the relationships among the music objects of a given piece while listening to an audio track and viewing the corresponding score. This is made possible by a new XML-based standard for music representation – namely IEEE 1599 – which will be shortly described.
