Bach's predecessor as cantor

Bach's predecessor as cantor, Johann Kuhnau, had also been music director for the Paulinerkirche, the church of Leipzig University. But when Bach was installed as cantor in 1723, he was put in charge only of music for festal (church holiday) services at the Paulinerkirche; his petition to also provide music for regular Sunday services there (for a corresponding salary increase) went all the way to the Elector but was denied.
