Écosystèmes audibles et structures sonores émergentes dans la musique d'Agostino Di Scipio. Une collaboration entre philosophie de la musique et analyse musicale

International audienceWhile composing with an ecosystemic approach, Di Scipio creates an audiosystem that interacts with the environment, i.e. space. This space, in which and from which musicemerges, is also the listener's space. The notion of emergence is complex: what emerges is theresult of a confrontation between the listener's cognitive system and the audio system used in themusical work. This emergent result can be termed musical "structure" or sound "structure", but itis difficult to define it with precision. Its general outline is unpredictable and unstable. It isdependent on a dynamic musical space, which is constructed by active listening and by activeaudio system simultaneously. To choose either the first or the second as a starting point for theemergent structures is impossible. "I am interested in composing desirable interactions amongavailable elements or components, such that the music is heard as the empirical epiphenomenon ofthat network of interactions, not as an abstract discourse written by me and diligently spoken byothers", says Di Scipio (2005a: 385). This is why his music is so difficult to analyse. Whileanalysing it, one must focus on the ephemeral moment where music emerges in the interactionbetween the listener and the product of the audio system, and inside a specific space.Cet article montre comment, en combinant analyse musicale et philosophie de la musique, on peut approcher la notion d' "écosystème audible" utilisée par Agostino Di Scipi
