Book excerpt: The sustainability of music and other intangible expressions of culture has been high on the agenda of scholars, governments and NGOs in recent years. However, there is a striking lack of systematic research into what exactly affects sustainability across music cultures. By analyzing case studies of nine highly diverse music cultures against a single framework that identifies key factors in music sustainability, Sustainable Futures for Music Cultures offers an understanding of both the challenges and the dynamics of music sustainability in the contemporary global environment, and breathes new life into the previously discredited realm of comparative musicology, from an emphatically non-Eurocentric perspective. Situated within the expanding field of applied ethnomusicology, this book confirms some commonly held beliefs, challenges others, and reveals sometimes surprising insights into the dynamics of music cultures. By examining, comparing and contrasting highly diverse contexts from thriving to 'in urgent need of safeguarding, ' Sustainable Futures for Music Cultures analyzes sustainability across five carefully defined domains. The book identifies pathways to strategies and tools that may empower communities to sustain and revitalize their music heritage on their terms. In this way, this book contributes to greater scholarly insight, new (sub)disciplinary approaches, and pathways to improved practical outcomes for the long-term sustainability of music cultures. As such it will be an essential resource for ethnomusicologists, as well as scholars and activists outside of music, with an interest in the preservation of intangible cultural heritage.
