I wrote about the opening sinfonia (or instrumental/concerto movement) in Bach’s Cantata 35 in an earlier post. Listening again, recently, to this incredibly beautiful solo cantata for alto, I was reminded that Bach actually included two sinfonias in the work. A second sinfonia presto opens Part II. Cantata 35 is the only cantata in which he included two sinfonias.
Bach probably adapted some of this material from his earlier compositions. Nevertheless, Cantata 35 exemplifies Bach at his absolute best!
Enjoy this recording of the sinfonia presto, performed here by the Choir and Orchestra of the J. S. Bach Foundation conducted by Rudolf Lutz.
