In 1668 Buxtehude got the job of organist at the Marienkirche in Lübeck in Germany. This was a very important job at one of the biggest churches in Germany. The organist before him had been a man called Franz Tunder. He had a daughter, Anna Margarethe, and Buxtehude married her. His job was not only to play the organ, but also to tune it and do a lot of administration in the church. He composed many cantatas for the services and organized five evening musical performances every year. These concerts were called “Abendmusik” (“Evening Music”) and were held at 4.00pm after the Evening Service. Unfortunately we do not know what music was performed at these concerts.
