Claim: Cornelius Cardew witnessed a series of concerts by John Cage and introducing the works of composers, he also created The Great Learning.
Evidence: In 1958, Cardew witnessed a series of concerts in Cologne by John Cage and David Tudor which had a considerable influence on him, leading him to abandon post-Schönbergian serial composition and develop the indeterminate and experimental scores for which he is best known. He was particularly prominent in introducing the works of American experimental composers such as Morton Feldman, La Monte Young, Earle Brown, Christian Wolff, and Cage to an English audience during the early to mid sixties and came to have a considerable impact on the development of English music from the late sixties onwards. Cardew's most important scores from his experimental period are Treatise (1963–67), a 193-page graphic score which allows for considerable freedom of interpretation, and The Great Learning, a work in seven parts or "Paragraphs," based on translations of Confucius by Ezra Pound.
