Nordoff-Robbins Music Therapy is an improvisational and compositional approach to individual and group therapy that resulted from the pioneering teamwork of Paul Nordoff and Clive Robbins over a period of 17 years. Nordoff and Robbins developed this approach for practical clinical purposes while working with the children at Sunfield Children's Home in 1959. This paper explores the critical academic year of 1959-1960 as a watershed in the early development of Nordoff-Robbins Music Therapy. By way of context, it also examines (a) how Paul Nordoff, as a distinguished American pianist and composer, became a music therapist; (b) how Nordoff's former musical career as a composer and pianist affected his clinical musicianship as a music therapist; (c) how Clive Robbins, as a British special educator, became a music therapist; (d) how their team work emerged; and (e) how they developed their own approach. In conclusion, the early development of Nordoff-Robbins Music Therapy resulted from Nordoff and Robbins' similar philosophical background, the supportive environment of Sunfield Children's Home, the guidance of Herbert Geuter, M.D., and their courage. Since the 1959-1960 academic years, the application and practice of Nordoff-Robbins Music Therapy has undergone many changes. However, the pioneering spirit of Nordoff and Robbins manifested in that watershed year remains strong among contemporary Nordoff-Robbins music therapy practitioners.
