Collegium Musicum has a choir of around 100 members. During the rehearsals we work on music from the great War Requiem of Britten to the intimate Ave Maris Stella of Bardos, and Chichester Psalms of Bernstein to the Quatre motets pour le temps de noël of Poulenc. You can find more examples on the concert page. Each semester this results in two concerts, on which we usually perform a large piece with orchestral accompaniment and a few smaller a cappella pieces.

Since March 2019 the choir has been conducted by conductor Gerrit Maas. During rehearsals, he is supported on the piano by our rehearsal David Dekker.


Future program

In June 2020 we perform the four works of Verdi Quattro pezzi sacri with the orchestra: Ave Maria, Stabat Mater, Laudi alla Vergine Maria and Te Deum.

In December 2020 we will give a concert on the theme of death. With the orchestra we perform Nänie van Brahms and Toward the unknown region by Vaughan Williams. The orchestra will play the Island of the Dead by Rachmaninoff and Danse macabre by Camille Saint-Saëns.
