The book provides detailed documentation of medical and psychological literature relating to music therapy practice which will be a rich resource for the music therapy practitioner and researcher. Hopefully, it will inspire a whole body of carefully constructed research based in practice. It leaves me with the overall feeling of a highly skilled and sensitive observer looking at and working alongside another profession. David Aldridge avoids a polarisation into differing camps and eventual political debate fostering a climate of tolerance that he views as a mark of a mature profession.
