Most of the european centers that were the essential and fertile ground for development of electronic and electro-acoustic music in the '50s and '60 were tightly connected to national radio networks. The Groupe de Recherche Musicales (GRM) of Pierre Schaeffer in Paris has been the nest of "musique concrete" in 1948, the Electronic Music Studio at the NWDR Koln (Nordwestdeutscher Rundfunk, born in 1951) has been the birthplace of the first electronic works of Karlheinz Stockhausen. During those same years two young italian composers, Luciano Berio and Bruno Maderna, started the adventure of the Studio di Fonologia Musicale - RAI in Milan. These activities and these composers (and many other artists along with them) were to become later the undisputed worldwide excellence in musical composition. Thus, these studios and their activity constitute at the same time one of the most outstanding successes and one of the most precious shrines of a culture that is essentially European. The aim of the project is to create a permanent installation at the Milan Museum of musical instruments, consisting of a SW-HW system that re-creates the electronic lutherie of the Studio di Fonologia Musicale (RAI, Milan, Italy): in particular the production setup that were originally used to compose the Pousseur's composition Scambi will be virtually recreated.This work will allow musicians from all over Europe to experience the re-appropriation of both Pousseur's composition and of the ancient analog technology that were used at that time through the virtual lutherie produced by the project. At the same time the installation will be the occasion for scholars to think about open compositions understanding by direct manipulation in this specific creative process. Furthermore they will learn a very important piece of history of modern Music: the birth of electronic music and its connection with the most important radiophonic european institutions.
