The Sitwells looked after their protégé both materially and culturally, giving him not only a home but a stimulating cultural education. He took music lessons with Ernest Ansermet, Ferruccio Busoni and Edward J. Dent. He attended the Russian ballet, met Stravinsky and Gershwin, heard the Savoy Orpheans at the Savoy Hotel and wrote an experimental string quartet heavily influenced by the Second Viennese School that was performed at a festival of new music at Salzburg in 1923. Alban Berg heard the performance and was impressed enough to take Walton to meet Arnold Schoenberg, Berg's teacher and the founder of the Second Viennese School.
