Codage, représentation et traitement du geste instrumental. Application à la synthèse de sons musicaux par simulation de mécanismes instrumentaux

Abstract : This work, mainly concerned with the conception and the elaboration of an informatic tool for musical creation deals with instrumental gesture in order to control in real time sound-synthesis processes, and to analyse its relationship with musical composition. This work is in two parts: 1/ a preliminary analysis of instrumental gesture typology leads to propose a coding which takes into account a spatial ant temporal organization of gestural information. We used these principles to conceive and realize an informatic system, which enables the coding and the pre-processing of gestural signals in real time. 2/ The study then focuses on searching a structural representation of gesture, which brings out some expressive features of gesture. A method which consists of identifying the gestural human action on a physical object with a simple but time-varying mechanical model, is proposed. This approach leads to a homogeneous description of both gesture and instrument which takes into account the coherency of the man-instrument interaction and can be used as a new way to manipulate structural characteristics of gesture.
