The Harvard University Department of Music is devoted to the study and practice of music, and exists to provide a first-rate musical education that gives students advanced skills in music as well as knowledge of music history and repertory. As an academic department it offers both an undergraduate and a graduate program: undergraduates receive an A.B. with a concentration in music and graduate students complete a Ph.D. program in historical musicology, ethnomusicology, theory, or composition. There is also a small A.M. degree program in Performance Practice and a dual-degree program (A.B./M.M.) run jointly with New England Conservatory. The Department sponsors numerous concerts, colloquia, lectures and special music events each month, which are free to students and the public.
