This book provides fresh insight into the creative practice developed by Paul McCartney over his extended career as a songwriter, record producer and performing musician. It frames its examination of McCartney's work through the lens of the systems model of creativity developed by Mihaly Csikszentmihalyi and combines this with the research work of Pierre Bourdieu. This systems approach is built around the basic structures of idiosyncratic agents, like McCartney himself, and the choices he has made as a creative individual. It also locates his work within social fields and cultural domains, all crucial aspects of the creative system that McCartney continues to be immersed in. Using this tripartite system, the book includes analysis of McCartney's creative collaborations with musicians, producers, artists and filmmakers and provides a critical analysis of the Romantic myth which forms a central tenet of popular music. This engaging work will have interdisciplinary appeal to students and scholars of the psychology of creativity, popular music, sociology and cultural studies.
