The Cathedral Orchestra
includes musicians from all the major Viennese orchestras. The orchestra appears in various forms spanning everything from chamber music ensemble to full romantic symphony orchestra.
The Cathedral Orchestra provides accompaniment for soloists and the choir, and also performs purely orchestral works. The orchestra can be heard at Sunday masses, countless other Dommusik services and concerts, and special events such as the Lange Nacht der Kirchen (The Long Night of Churches).
