Graupner composed a lot of cantatas in Darmstadt. In 1722 he was chosen to become the "Kantor" of the Thomaskirche in Leipzig. A "Kantor" is a musician who manages the music in a church. However, Graupner decided to remain in Darmstadt. That is because his employer increased his salary. Instead, Johann Sebastian Bach became the next "Kantor" of the Thomaskirche.
