Why is BWV 231 spurious? It is the second movement of cantata BWV 28,from which the text has been altered and the basso continuo omitted (which in the cantata mostly doubled the vocal bass).

- You’ve answered your own question. The authentic version is the second movement of BWV 28; presumably the view of Bach scholarship is that the motet BWV 231 is a contrafactum of Bach’s work, made without any authority from the composer, and hence is spurious despite embodying music that he composed.
