MUSIC STRUCTURE REPRESENTATION: A FORMAL MODEL

International audienceIn the present work we introduce a general formal (Object Oriented) model for the representation of musical structure information, taking into account some common feature of the information vehiculed by music analysis. The model is suitable to represent many different kinds of musical analytical entities. As an example of both musical and mathematical-computational relevance, we introduce the D.Lewin's GIS theory. A GIS is equivalent to a particular kind of group action over a set: we show that other related structures can be treated in a similar manner. We conclude with the prototype implementation of these ideas in MX, an XML format for music information
