Here's what we know about his musical output:
* He was primarily a church musician. This is likely why most of his compositions were intended for religious services, such as cantatas, motets, and organ works.
* He is believed to have written several cantatas and chorales. Unfortunately, none of these have been preserved.
* He also wrote a few keyboard pieces. Some of these are still extant, including "Allein Gott in der Höh sei Ehr" and "Christ lag in Todesbanden," which are considered early examples of Baroque organ music.
It's crucial to remember that our knowledge of Johann Christoph Bach's work is very limited due to the lack of surviving manuscripts. Therefore, it's impossible to provide a comprehensive list of his compositions.
However, the surviving works offer valuable insight into the musical environment in which Johann Sebastian Bach grew up and was influenced.
