Analyse, représentation et traitement du geste instrumental : application aux instruments à clavier

Abstract : This thesis is part of the design and achievement of a computer tool for musical creation. It deals with the question of instrumental gesture in order to control in real time sound synthesis processes by means of simulating instrumental mechanisms, and to study its relation with musical composition. We pose the problem of segmentation to describe and classify the instrumental gesture, assimilated as a sequence of gestural events, received and memorized in form of sampled signals. We consider the play with keyboard instrument, we propose elements of a gestural syntax, and deduce criteria for an automatic segmentation. Then we take interest to the graphical representation of the segmented gestural events, and to their transformation and composition. We define several levels of representation and, for each level, manual processing procedures or compositional models procedures, in full or in part. The gesture editor, integrated in the sound synthesis system CORDIS-ANIMA, combines all these possibilities.
