At the age of sixteen Walton became an undergraduate of Christ Church. It is sometimes said that he was Oxford's youngest undergraduate since Henry VIII, and though this is probably not correct, he was nonetheless among the youngest. He came under the influence of Hugh Allen, the dominant figure in Oxford's musical life. Allen introduced Walton to modern music, including Stravinsky's "Petrushka", and enthused him with "the mysteries of the orchestra". Walton spent much time in the university library, studying scores by Stravinsky, Debussy, Sibelius, Roussel and others. He neglected his non-musical studies, and though he passed the musical examinations with ease, he failed the Greek and algebra examinations required for graduation.
