Spiritus Ensemble is a semi-professional choral-instrumental ensemble of 18 voices plus an orchestra of varying size that performs mainly the liturgical music of J.S. Bach and other music of the German Baroque. We perform four or five times a season in Kitchener-Waterloo, sometimes in concert and sometimes in a Bach Vespers format. Rehearsals take place on the two or three Saturday mornings preceding each performance. Performances are on Sundays at 4pm. During the 2017/18 season, Spiritus will perform Bach’s Cantatas 30, 79, and 98, as well as music by other composers Buxtehude, Mendelssohn, and Mozart.
