Brandenburg Concerto No. 3: movement 2

For our second installment in the Brandenburg Concerto 3 miniseries, Christian describes the whole 20-second middle movement: chord 1, chord 2. Well...no, that isn't the whole story. We will uncover much more than meets the eye in this shortest of all Bach movements. It's an automatic "moment" -- no cutting or zooming in necessary.
