LA MUSICA ELETTRONICA E IL RESTAURO DEI DOCUMENTI SONORI (Rev.1180 2008-10-05) Nicola Bernardini Conservatorio “C.Pollini”, Padova Alvise Vidolin Conservatorio “B.Marcello”, Venezia Sommario Computer Music is over fifty years old and a meditation over the relation- ship between music and technology is order, possibly extending it to the social and cultural context in which this discipline was born. The planetary polit- ical system where computer music was born was characterized by a strong antagonism between two ideological blocks in which culture had a tremen- dous impact in occidental countries to demonstrate the advantages and the richness of democratic, progressive and innovative societies. The end of this antagonism has generated a steep decrease of interest in cultural investments by the occidental countries, and computer music has evolved in the present sound and music computing : a much wider interdisciplinary field which en- compasses many areas where the combination of sound, music and information technologies still produces brilliant results. This paper will also develop some of the current issues at stake in the sound and music computing area: 1. the rise of the commercial Internet has revolutionized the concept of “in- tellectual property”, enhancing the concept of authorship in contrast to the droit d’auteur and promoting a liberated distribution of knowledge; 2. the virtualization of containers will reestablish a value of contents ; 3. Libre Software has had a completely unexpected development, providing many applications to music too; 4. P2P technologies which facilitate the copy of contents over networks will provide the most powerful antidote against the loss of memory, thus helping out the recovery and diffusion of musical works which would be confined into oblivion otherwise. 1 Introduzione Nel 1994, gli autori di questo saggio scrissero una breve panoramica delle risorse eco- nomiche alla base della ricerca e della produzione nel campo della musica elettronica 1
