Roger Sessions

Roger Huntington Sessions was an American composer, teacher, and writer on music. He had started his career writing in a neoclassical style, but gradually moved towards complex harmonies and postromanticism, and finally the twelve-tone serialism of the Second Viennese School. Sessions's friendship with Arnold Schoenberg influenced him, but he modified his technique to a unique style involving rows to supply melodic themes, while composing subsidiary parts freely.
