NINA - Navigating and Interacting with Notation and Audio

This article deals with an XML-based format that allows an integrated representation of music, as well as with a working software demo that demonstrates the power of the format. The format itself is the basis of an IEEE international standard for a comprehensive description of music contents and their synchronisation. After a theoretical introduction, a music browser based on such concepts will be reviewed. The application, called NINA (for Navigating and Interacting with Notation and Audio), has been recently presented at an exhibition about Neapolitan music.
