Profound theoretical and philosophical approach to contemporary music'Unsayable Music' presents theoretical, critical and analytical reflections onkey topics of contemporary music including acoustic, electroacoustic anddigital music, and audiovisual and multimedia composition. Six essays byPaulo C. Chagas approach music from different perspectives such as philosophy,sociology, cybernetics, musical semiotics, media, and critical studies.Chagas's practical experience, both as a composer of contemporary musicand sound director of the Electronic Music Studio of Cologne, nourisheshis observations on the specific creativity that emerges with the use of thetechnical apparatus, the development of the electronic music studio, thedifferent aesthetics of electroacoustic music, and the forms of audiovisualand multimedia composition. The title 'Unsayable Music' is a reference toWittgenstein, who suggested that sound is only the surface of music andthat the musical work conceals something more profound that can hardlybe described by philosophical models or scientific theories.
