Prior to graduation, every Performance major must have had appropriate literature courses in the major area, either on the undergraduate or the graduate level. For pianists, this means Piano Literature; for singers, this means both Song Literature (if the student had Song Literature at the undergraduate level, this suffices) and Opera Literature; for orchestral instrumentalists, this means both Orchestral Instrument Literature and Chamber Music Literature. Piano, Song, Opera, and Orchestral Instrument Literature classes are 500-level courses. Chamber Literature is a 600-level course. All graduate students must take at least one 600-level. Literature classes are offered on a 2-year rotation; graduate students must take their required literature course at the time they are offered.
