Johann Christoph Bach (musician at Arnstadt)
Johann Christoph Bach (22 February 1645 in Erfurt – 7 September [O.S. 28 August] 1693 in Arnstadt) was a German musician of the Baroque period.
He was the third son of Christoph Bach and the twin brother of Johann Ambrosius Bach. In 1671, Johann Christoph received an appointment as court violinist at the Arnstadt court. Disputes arose within the Stadmusikus Gräder (city musicians), and all the musicians were promptly fired. Shortly after, the sovereign Anton Günther I died, which induced a ban on all public music. Bach found himself in great need. However, at the beginning of 1682, he was reinstated at court by the new ruler Count Günther von Schwarzburg - Arnstadt. He was the uncle of Johann Sebastian Bach, and is credited with introducing him to the organ. He married Martha Elisabeth Eisentraut (1654-1719).
The funeral aria Nun ist alles überwunden is commonly attributed to him.
