Welcome back to our yearly miniseries on the Brandenburg Concertos of J. S. Bach! This is part two of three. Today we look at the languid and luscious slow movement of Brandenburg Concerto No. 6.
Music is (often) a setup of expectations, and then the satisfying fulfillment of those expectations OR the clever subversion of those expectations. Bach is especially good at this principle. We focus first on the unusual written-out cello part, separate from the basso continuo, creating a new entity but bound to the bass still (heterophony). Then we look at Christian's two moments, both of expectation and then subversion.
