Hans Keller

Hans (Heinrich) Keller (11 March 19196 November 1985) was an Austrian-born British musician and writer, who made significant contributions to musicology and music criticism, as well as being a commentator on such disparate fields as psychoanalysis and football. In the late 1950s, he invented the method of "wordless functional analysis", in which a musical composition is analysed in musical sound alone, without any words being heard or read. He worked full-time for the BBC between 1959 and 1979. Provided by Wikipedia
