(What God doth, that is rightly done) for soprano, alto, tenor and bass, vocal ensemble, horn, transverse flute, oboe d‘amore, strings and continuo

Written for 17 September 1724, BWV 99 belongs to the substantial chorale cantata cycle of 1724/25, and is one of three cantatas all beginning with the same hymn. While it may be that Bach omitted the organ in movements two to five to underscore the contrast between the traditional chorale in full ensemble sound and the cantata’s freely versed arias and recitatives, this interpretation remains pure conjecture: although the part is marked “tacet” in Bach’s own hand in the source documents, this cannot be dated with certainty and may relate to a later performance.
