This breezy little two-line chorale doesn't seem like much, but it is Bach's setting of a tune that was very well known -- the German Magnificat.  This leads us down a rabbit hole of discussion about how this performance relates to BWV 10, a cantata that Bach based on this same tune.  We explore the tune and its psalm tone, and we delight in the way Bach sets the words "ewigkeit zu ewigkeit" (eternity to eternity) as continuous, neverending, rising figures in the choral parts.
