From 1958 to 1960 Paul Nordoff worked in Sunfield Homes together with Michael Wilson and Dr Herbert Geuter, the son of founder Fried Geuter, both accomplished musicians conversant with the field of music therapy themselves.
Thereafter, they worked together in a research programme beginning in 1961 for two years, in which they treated children with severe handicap in public schools in Philadelphia by means of music therapy, with astonishing results on their ability to learn.
