Jan Dismas Zelenka
The Kapellmeister in Dresden at that time was Johann David Heinichen. Because Heinichen was often ill, Zelenka managed the sacred music in Dresden. When Heinichen died in 1729, Zelenka became an acting Kapellmeister. He finally became a Kapellmeister in 1734. In 1726, Zelenka started a list of works composed by the composers in Dresden. This list is called the Inventarium. It is an important document for Dresden baroque music.
