What is the role of music and sound in addressing the environmental crisis? In search of answers, I undertook an eco-ethnomusicological study of music and sound as responses to the cultural rupture between humans and the natural world that lies at the heart of the crisis. This lecture draws on case studies from applied research and artistic practice focused on sound-mediated forms of environmentalism in my native region of Central Italy. There I investigated how cultural, conservation, and environmentalist organizations—together with individual artists and performers—use sonic practices to foster ecological awareness, action, and reconnection. Building on this fieldwork experience, I ultimately reflect on the contribution of music and ethnomusicology in creating a more ecocentric society.
