Paulo C. Chagas is Professor of Composition at the University of California, Riverside (USA). A very versatile composer, Chagas has written over 150 works for orchestra, chamber music, electroacoustic music, audiovisual and multimedia compositions. His music unfolds a pluralistic aesthetic, using the most diverse musical materials from different cultures, acoustic and digital media, dance, video, and audiovisual installations. The creative manipulation of electronic and digital sound and the integration of music into multimedia forms is a significant aspect of Chagas’ work. His works are performed in the US, Europe, Russia and Brazil. Chagas is also a prolific author. His scholarship is focused on musical semiotics, philosophy, electroacoustic and digital music. His most recent book Unsayable Music (Leuven University Press, 2014) presents theoretical, critical and analytical reflections on key topics of contemporary music.
