Pianist-author Charles Rosen will be the 1980-81 Charles Eliot Norton Professor of Poetry. Rosen, who won the 1972 National Book Award for his "The Classical Form: Haydn, Mozart, Beethoven," will give six Norton lectures and two recitals of Beethoven piano pieces next year.

The lectures will probably cover romanticism in music, Henri T. Zerner, professor of Fine Arts, said yesterday.

Rosen will also teach a course on the music of the 1820s next fall and a graduate tutorial next spring, Luise Vosgerchian, Naumburg Professor of Music and chairman of the Music Department, said yesterday.

Rosen is currently a professor of music at the University of New York State at Stonybrook. He earned his Ph.D. in French literature at Princeton.
