Gott fähret auf mit Jauchzen, BWV 43

[4] The cantata is closed by the first and thirteenth stanza of Johann Rist's hymn "Du Lebensfürst, Herr Jesu Christ" (1641).

[2] The cantata is festively scored for four vocal soloists (soprano, alto, tenor and bass), a four-part choir, three trumpets, timpani (tamburi in the autograph[6]), two oboes, two violins, viola and basso continuo.

The New Testament quotation is sung not by the bass as the vox Christi but, likely because Jesus is not speaking himself, instead the soprano narrates "So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God" as a secco recitative.

The bass aria is highlighted by an obbligato trumpet part, but it is so difficult that Bach gave it to a violin in a later performance.

The words "voll Schmerzen, Qual und Pein" (full of sorrow, torment and pain)[1] are illustrated by a slower tempo and harmonic tension.

The last aria, accompanied by the oboes, enjoys the victory over the enemies, in a vision of peace rather than a description of a battle,[2] but stresses the words "aus Jammer, Not und Schmach" (out of suffering, distress and ignominy)[1] by "harmonic darkening".

[3] The closing chorale is a four-part setting of the melody of Ermuntre dich, mein schwacher Geist, composed by Johann Schop in 1641.
