The author describes how, in practice, music therapists work at child day care centres, adult day care centres and in other institutions. The first chapters cover the history and theory of working with music with people with developmental disabilities. The main body of the book covers discussion of the various methods, including individual and group work. Each method is described in terms of the clinical indications, the objectives set and the choice of techniques and musical instruments, and is illustrated through the use of case study. The final chapter draws conclusions for both theory and practice.
