Successor to Franz Tunder at Lübeck's Church of Mary in 1668, Buxtehude began the tradition of Abendmusiken five years later. The annual concert series began the fifth Sunday before Christmas and featured sacred works for organ, choir and orchestra (a lasting tradition in that church for 137 years). In 1705 Bach walked 250 miles from Arnstadt to attend the Abendmusiken and overstayed his leave by three months. Buxtehude was known in his lifetime chiefly as an organ virtuoso and teacher whose students included Bruhns. In a letter to Forkel, Carl Philipp Emanuel identified Buxtehude as a composer whose works his father much admired.
