You say you want a revolution....we all want to change the world..." With those 1968 lyrics John Lennon and the Beatles implicitly gave voice to the widespread 1960s belief that music could effect change in the "real world." This course asks how, in the hope of making musical activists of us all. How, that is, has music been used in the last century as a means of effecting social change? Do the answers depend on whether music is used by non-state actors, corporate actors, or the state? on the traditions and habits of the community to be changed? on qualities of the music? Does music remain a viable medium for social change, or has it been replaced by explicitly non-musical acoustical behaviors? How can we use music (and sound) now to effect social change? Reading, discussion, collective music-making in class; one oral (group) presentation during the semester. Final project is to design (and, if it is safe, execute and evaluate) a musical 'action' aimed at producing social change in your world.
