What shapes our music technologies? How do our technologies shape our musical practices and thought? An exciting body of scholarship has addressed such questions for sound recording, electronic instruments and digital media, illuminating the development and adoption of new technologies and their consequences for the creation, circulation, consumption and conception of music. Yet older technologies too were once new – and new technologies often revive or perpetuate old values, compromises and assumptions in unrecognized ways. This conference aims to question and illuminate the acoustic/electronic and analog/digital divides by addressing “new” music technologies from across history, from notation systems to sound recording, string instruments to synthesizers, carillons to computers, metronomes to MIDI – from bone flute to auto-tune. The conference also aims to open up dialogues between past and current practice by bringing together scholars, musicians and inventors from the Bay/Silicon Valley Area and beyond.
