Production of Immersive Musical Architecture by Physical Modelling of Self-Sustained Oscillating Structures

International audienceThis paper presents the first results of a study on physical modelling of self-sustained oscillating structures, that was carried out with the sound synthesis and musical creation environment GENESIS. This study aims at producing sounds with rich timbre and, at a compositional level, at building immersive complex musical architectures. Indeed, based on the mass-interaction CORDIS-ANIMA physical modelling formalism, GENESIS has got the noteworthy property that it allows to work both on sound itself and on musical composition in a single coherent environment. So generic tools to model self-sustained oscillating structures are developed and analysed in order to work on rich timbres and on the temporal macrostructure of the music, that is of the gesture and the instrumental performance, as well as the composition. In fact, we use the complex motion of a bowed macrostructure as a musical events generator which behaviour may simulate an expressive "instrumental performance" and lead to evocative and immersive musical architectures
