The graduate students in the music department will present two Saturday night concerts of works they have written in seminars this year, representing what one called the culmination of a year's toil that through performance should prove this department is interested in doing more than analyzing notes in a score. Titles of the pieces range from the traditional trio for clarinet, violin and piano to one called "Tuesdays are always yellow, aren't they?" for harp and it's-anyone's-guess-what-else. Although Harvard does not have the most illustrious name as far as graduate music schools go the composition professors are outstanding and their students are a highly select and qualified crew.
