The Harvard–Radcliffe Collegium Musicum is a mixed chorus at Harvard University, composed of roughly 50 voices from undergraduate and graduate student populations. Founded in 1971 to coincide with the coeducational merger of Harvard and Radcliffe College, Collegium drew from members of the Harvard Glee Club and the Radcliffe Choral Society to form a smaller mixed group that could represent Harvard on tours. Although Collegium used to perform primarily early Renaissance music, its repertoire now draws from centuries of a cappella and orchestral selections. Together with the (tenor-bass) Harvard Glee Club and the (soprano-alto) Radcliffe Choral Society, it is a member of the Harvard Choruses. History F. John Adams served as Collegium's conductor from its founding until 1978, when Jameson Marvin became Harvard's Director of Choral Activities. The group rose to prominence during Marvin's thirty-two-year tenure, receiving critical acclaim through recordings, international tours, and numerous invited appearances at professional conferences. Andrew Clark became Collegium's third conductor in 2010 and has led the ensemble in performances of Bach's Saint Matthew Passion, Handel's Israel in Egypt, Mozart's Requiem, Haydn's The Creation, Rachmaninoff's All-Night Vigil (Vespers), and Arvo Pärt's Saint John Passion, as well as in appearances at Boston's Jordan Hall, the Metropolitan Museum of Art in New York, Salzburg Cathedral, and St. Stephen's Cathedral in Vienna. Recent Concert Seasons 2019–2020 On March 7, 2020, Collegium held a closed concert to an empty Sanders Theater due to mounting fears from administration at Harvard University about COVID-19. The group persisted with the performance, live-streaming the event to over a thousand viewers from around the world. It was at this concert that they debuted the piece Wander composed by Harvard Undergraduate Ian Chan, and presented To the Hands by Caroline Shaw and Mozart's Requiem as completed by German composer Michael Ostrzyga. 2018–2019 As in recent even-numbered years, Collegium collaborated with the Radcliffe Choral Society for a programmatic fall concert. This concert, Compassion, featured Monteverdi's Sestina Lagrima d'Amante and Bach's motet Der Geist Hilft. In the winter, Collegium presented the East Coast Premiere of How to Go On, an a cappella secular requiem by Dale Trumbore. On May 3, 2019, Collegium joined forces with all the Harvard Choruses to perform Vaughan Williams' indomitable Sea Symphony. 2016–2017 Collegium began the year with One Music: A moving mosaic celebrating the gift of song, which featured the world premiere of Harvard alumnus Robert Kyr's In the Name of Music.
