The Calixa-Lavallée Ensemble is the chamber choir of the School of Music of the University of Ottawa. Participation in this ensemble, which is conducted by Laurence Ewashko, allows singers to expand their knowledge in many ways: by performing a wide variety of vocal styles and repertoire; by developing a sense of blend; and by improving their sight-reading, linguistic, and vocal/choral ensemble skills. The Calixa-Lavallée Choir performs regularly throughout the school year in a variety of concerts, both at the university and within the community at large.
