L'improvisation musicale électroacoustique : enjeux et problématiques du développement des technologies numériques

Abstract : This research/creation thesis is centred on the exploration of musicians’ needs for the practice of electroacoustic music improvisation. This investigation was conducted through participant observation with different musical ensembles. It also presents the strategies adopted for the development of digital tools in the case of a created musical instrument. How does the practice of free improvisation in electroacoustic music work and what knowledge is needed to achieve free improvisation? To answer these questions, several paths were taken: for example considering the context of the performance and by challenging the musical and extramusical aspects surrounding the improvised action. Furthermore, this research deployed a study of the characteristics of a digital instrument that endeavours to possess the same flexibility as acoustic instruments. The “creation” component of this thesis is through the development of a digital instrument (RJ). This instrument is implemented with a sound samples recommendation system. It was used in situation of improvisation with several ensembles, which form part of the corpus of data of this thesis. Lastly, this thesis seeks to characterize musical improvisation through the multiple interactions that occur during an improvised performance. The research therefore provides a practical and theoretical framework for the use and exploration of contemporary digital tools for musicians, which practice collective free improvisation.
