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. Curricular deficiencies in these areas may be removed with either undergraduate or graduate credit. 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.
