Johann Sebastian Bach composed the church cantataWas Gott tut, das ist wohlgetan (What God does is well done),[1]BWV98, in Leipzig for the 21st Sunday after Trinity and first performed it on 10 November 1726.
Recitative (tenor): Ach Gott! wenn wirst du mich einmal
Aria (soprano): Hört, ihr Augen, auf zu weinen
Recitative (alto): Gott hat ein Herz, das des Erbarmens Überfluß
Aria (bass): Meinen Jesum laß ich nicht
Music
The cantata is scored like chamber music, especially compared to the chorale cantatas on the same chorale with a melody by Severus Gastorius.[6] In the opening chorus, the mostly homophonic setting of the voices, with the oboes playing colla parte, is complemented by strings dominated by the first violin as an obbligato instrument rather than an independent orchestral concerto. The final line is in free polyphony, extended even during the long last note of the tune. All voices have extended melismas on the word "walten" (govern), stressing that God is "ultimately in control". Strings and voices alternate in the bar form's two Stollen, but are united for the Abgesang.[2][4]
Both recitatives are secco. The first aria is accompanied by an obbligato oboe. The first two measures of its theme are derived from the chorale tune. The ritornello is repeated after a first vocal section, "cease weeping and remain patient", and a second time, concluding a different vocal section, which renders "God's resoluteness" in a stream of triplets in the voice.[4] The second aria is the final movement, dominated by the violins in unison in a similar structure as the first, two vocal sections framed by repeats of a ritornello.[4] Bach hints at the regular closing chorale by beginning the vocal part with an embellished version of the first line of the hymn "Meinen Jesum laß ich nicht" on a melody by Andreas Hammerschmidt[7] on the same words as the cantata text. The first line appears in four of five entries of the voice.[4]
