The UM School of Music owns a large collection of historical instruments, including several recorders, crumhorns, sackbuts, cornets, shawms, curtals, viols, rebecs, a hurdy gurdy, harpsichords, a positive organ, a pianoforte, and baroque bows for stringed instruments. Students often learn how to play these instruments for the first time in the Collegium, but satisfactory musicianship is a prerequisite. The ensemble has traditionally consisted of both UM students and more experienced early music performers from the Washington D.C. community. UM students are required to register for the Collegium Musicum as a course, and they receive a syllabus with a rehearsal and concert schedule, a list of readings, and other required activities and assignments. The assignments improve their understanding of early music in general as well as of the compositions they perform.
