Many young people rely on music to guide them through the good and bad times of their lives. Whether immersing themselves in music to process emotions or creating music as a means of self-expression, it provides a powerful outlet that can help young people navigate the turbulence of adolescence. Centred around the three key areas of emotion, identity, and connectedness, the Handbook of Music, Adolescents, and Wellbeing provides insights into the relationship between music and young people, exploring questions such as: why do teenagers have such a passionate relationship with music? Why this is even more apparent and important during times of difficulty? How can music be utilised to enhance wellbeing? With 26 authors from around the globe, this book canvasses a wide range of perspectives, from the most scientific to the most practical. Each chapter contains insightful stories from the authors'' own experiences working with young people, and brings together the latest theory, research, and practice from the fields of music therapy, music psychology, music education, and music sociology to explore and understand how and why music plays such a big part in young lives. The first section addresses the popular topic of music and emotions, clarifying the ways that young people can learn to use music intentionally to achieve healthy outcomes. The second section looks at identity construction, emphasising agency in the ways that young people choose to express themselves both personally and to others. The third section explores connectedness, with a particular emphasis on uses of technology to connect with others. This book will be of interest to music therapists, youth and social workers, psychologists, counsellors, occupational therapists, teachers, parents, and anyone interested in promoting adolescent wellbeing through music.
