Abstract:

Segmentation is one of the main tasks within the musical analysis. We can say that segmentation is the partition of a musical flow into homogeneous segments, accordingly to certain criteria. These criteria are particular to each analytical model. This paper discusses some questions related to a musical analysis methodological model based on the concept of sonic object. In this model, a sonic object may be defined as the combination and interaction of multiple musical components and a gap in the continuity of at least one of these components may identify, in theory, a new structural/logical unit (a new sonic object). This paper is also concerned with the automatization of this process. We propose the use of the concept of rational agent for the segmentation of musical flows. Although the research is still in an early stage, we present some insights concernig the use of this concept in the segmentation of musical flows.
