Music plays an important role in all our lives, and is a channel through which we can express emotions, thoughts, political statements, and social relationships. However, just as music can be a channel through which we express ourselves, it can also have a profound influence on our own developing sense of identity. This is the first book to explore the powerful effect that music can have as we develop our sense of identity, from adolescence through to adulthood. Bringing together leading experts from psychology and music, it will be a valuable addition to the music psychology literature, and essential for music psychologists, social and developmental psychologists, and educational psychologists.
