In 1950, Copland received a U.S.-Italy Fulbright Commission scholarship to study in Rome, which he did the following year. Around this time, he also composed his Piano Quartet, adopting Schoenberg's twelve-tone method of composition, and "Old American Songs" (1950), the first set of which was premiered by Peter Pears and Benjamin Britten, the second by William Warfield. During the 1951–52 academic year, Copland gave a series of lectures under the Charles Eliot Norton Professorship at Harvard University. These lectures were published as the book "Music and Imagination".
