This work brings together the experiences of practitioners who use group music therapy with diverse client groups in various settings. Chapters discuss work with children, adolescents, and adults of all ages, shiwing the wide range of applications for group music therapy: in assessment for clinical diagnosis; in work with clients who have learning disabilities, special educational needs, eating disorders or autistic spectrum disorders; and in neurological rehabilitation. Group music therapy is examined from different theoretical perspectives - including psychoanalytic and Foulkesian approaches - and in conjunction with art therapy.
