Most of these pdf and audio files of the 371 Bach Chorale harmonizations are derived from MusicXML files produced by Margaret Greentree. In many cases I also consulted the published scores. Choral versions of all these chorales may be found on YouTube by searching for the BWV number. If the chorale is in a cantata, it is usually (but not always) at the very end.
This Chorale is not by Bach, who for unknown reasons took the closing Chorale to BWV 43 from the 1682 Leipziger hymnbook of Christoph Peter with only minor changes.
