One of the surviving works of Andreas Kneller is a set of eight variations on “Nun komm der heiden Heiland. Variations IV and V of the set variations on “Nun komm der heiden Heiland” are also found in manuscript Mus. Ms. 22541 of the Berlin Staatbibliothek. I present them as seperate pieces. The manuscript of Walther does as well, and I have no information about the adjoining phrases. The music is strong enough, I think, to stand on itself.
