This ensemble allows singers to expand their knowledge by performing a wide variety of vocal styles and repertoire, and developing a sense of blend; and by improving their sight-reading, linguistic, and vocal/choral ensemble skills. There is no audition requirement. Participation is compulsory for all undergraduate music students in their first and second year who are not involved in the orchestra. Director Laurence Ewashko divides the rehearsals into three sessions per week: one women’s sectional, one men’s sectional and one joint rehearsal. Each session is 1-½ hours in duration. The Choral Ensemble performs at three major events during the academic year: the university’s Musical Offering for Christmas in early December, the Intervarsity Choral Festival and the year-end concert of the University of Ottawa Orchestra.
