The mission of the Bach Cantata Choir is to sing the entire set of sacred cantatas by Johann Sebastian Bach over 30 years. The choir performs four cantata concerts per year – one or two cantatas per concert – as well as an annual Holiday Baroque concert. Cantatas are chosen to closely match the liturgical time of the year for which Bach wrote them. Concerts are scheduled for Sunday afternoons at 2pm. Singers come from many different choirs in the Portland area.
