The choir of c. 140 voices is mainly concerned with the musical part in services at the cathedral.

Every year, a small group of new singers is educated to join the choir.

The repertoire consists of church music by Johann Sebastian Bach, Joseph Haydn, Wolfgang Amadeus Mozart, Ludwig van Beethoven, Franz Schubert and Anton Bruckner.

The choir has toured several countries in concert, including Italy, France, Belgium, Switzerland, Israel, Russia, the US, Canada and Brazil.

Heinrich Hain was conductor to 1985, succeeded by Domkapellmeister Mathias Breitschaft to 2012, and then Karsten Storck [de].
