J.S. Bach’s Christmas Oratorio was written for the Christmas season of 1734, and although it incorporates music from earlier works it belongs firmly among his timeless large-scale compositions. The development of the oratorio, which was to become a new musical form in Protestant church services at that time, was stimulated by Bach’s compositions, particularly by the unusual form of his six-part Christmas Oratorio. From its famously joyful opening ‘Jauchzet frohlocket’ to the arrival of the Wise Men from the East, this work’s enduring popularity has long proven its status as a choral ‘evergreen’.
