Buxtehude stayed in this job for the rest of his life. He never travelled very far. Nicolaus Bruhns was one of his pupils, and Pachelbel wrote a piece of music called "Hexachordum Apollonis" for him. In 1706, when Johann Sebastian Bach was 21, he got permission for four weeks holiday so that he could go to Lübeck to hear Buxtehude play. He stayed in Lübeck for four months and so he got into trouble when he went back to his job at Arnstadt.
