Was Gott tut, das ist wohlgetan, BWV 100

Was Gott tut, das ist wohlgetan (What God does is done well), BWV 100, is a church cantata by Johann Sebastian Bach. He composed it in Leipzig between 1732 and 1735. The chorale cantata is based on the hymn by Samuel Rodigast (1674).

This work is a late chorale cantata for an unspecified occasion. Bach likely composed and first performed it in Leipzig between 1732 and 1735. This is considered one of Bach's latest extant church cantatas.

The cantata is based on the hymn "Was Gott tut, das ist wohlgetan" (1674) by Samuel Rodigast. This chorale was traditionally used in Leipzig as a song for weddings. Unlike most of Bach's earlier chorale cantatas, he used the text unchanged.

Bach performed the cantata again in 1737 and 1742.

The work is scored for four vocal soloists (soprano, alto, tenor, and bass), four-part choir, two horns, timpani, flauto traverso, oboe d'amore, two violins, viola and basso continuo.

The cantata has six movements, each verse beginning with "Was Gott tut, das ist wohlgetan"; the lines shown below are the second lines of each part.

Only the first and last movements use the chorale melody, while the inner movements adopt "carefully graduated sound colors". The rising fourth of the chorale melody, however, recurs throughout the cantata.
