The aim of the DREAM 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 considered. 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.
