Bach: Kantate BWV 80 Ein Feste Burg Ist Unser Gott (Viool 1)

This cantata can be traced back to two earlier works by Bach: The original work was the cantata “Alles, was von Gott geboren” (Weimar, 1715, BWV 80a); a second version (BWV 80b) was composed in Leipzig between 1727–1731. The simple chorale movement which opens the second version is printed in the appendix of this version of the cantata (BWV 80).
