Emergence of Sound, Sound of Emergence. This paper is in three parts. The first one introduces the notion of "sonological emergence” in the framework of a systemic perspective, following a radical-constructivistic standpoint. The secondo describes the main points in a compositional project, Ecosistemico Udibile (Audible Ecosystemics), consisting in a network of element processes capable of generating/ transforming/ destroying sound, working under real-time constraints, coupled with the space surrounding. The third part, articulates the auto-écoorganisation in the sonic network described, and advances some more general considerations of systemic and epistemologic kind. The discussion bears on the selfproducing (conditions of existence) and self-differentiating (conditions of form) elements in the process by which sound is produced, yielding into a generalisation of the music-theory notion of “ timbre”. The discussion also bears on how the systemic conditions (internal and external contraints, resources available in the environment) are dealt with in the real-time performance, when sound is recognized not only a “ energy” dimension (phisical substratus) but also an “ information” dimension (sound as interface, as regulator of system resonances). The notion of emergent sound, as emergent musical “ form”, is finally re-articulated in connection to the environment (space as the “ médium” or mileu of acoustical existence).
