Der Himmel lacht! Die Erde jubilieret, BWV 31
History and words. On 2 March 1714 Bach was appointed concertmaster of the Weimar court capelle of the co-reigning dukes Wilhelm Ernst and Ernst August of Saxe-Weimar. As concertmaster, he assumed the principal responsibility for composing new works, specifically cantatas for the (palace church), on a monthly schedule. Bach composed the cantata for Easter Sunday in 1715. The prescribed readings for the feast day were from the First letter to the Corinthians, "Christ is our Easter lamb" (), and from the Gospel of Mark, the Resurrection of Jesus (). The text was  written by the Weimar poet Salomon Franck who published it in (Evangelical Devotional Offering). The verses consist purely of free poetry and interpret the Easter message, connected to the request to believers to let Jesus also be resurrected within their souls. The final movement, the last verse of the chorale "" (When my hour is come) by Nikolaus Herman, expresses the desire to die, to follow Jesus in resurrection. Bach first performed the cantata on 21 April 1715. Looking at the rich scoring of three instrumental groups and a five-part choir, John Eliot Gardiner suggests that the cantata was not  performed in the court's small , but in the town church St. Peter und Paul, where the ducal family evidently at times attended services. Bach later performed the cantata several times in Leipzig in a slightly modified form. There is proof of performances for the years 1724 and 1731; a further performance in 1735 is probable as well. Since the Weimar tuning of the organ, which served as a reference for the string instruments, was probably a third higher than the standard tuning tone in Leipzig, Bach had to either leave out the voices of the reed instruments or rewrite  them for the Leipzig performances, or to replace the parts by different instruments. Scoring and structure. The cantata in nine movements is festively scored for three vocal soloists (soprano, tenor and bass), a five-part choir (SSATB), three trumpets, timpani, three oboes, taille (tenor oboe), bassoon, two violins, two violas, two cellos and basso continuo. The scoring for five parts in the choir, five parts in the woodwinds and six parts in the strings is unusual. Music. The festive character of the work is demonstrated by a sonata with a fanfare-like introduction, a concerto of the three groups brass , reeds and strings, all divided in many parts. The first choral movement, sung by a five-part chorus, evokes the "celestial laughter and worldly jubilation" of the text, according to John Eliot Gardiner, who continues: The bass voice announces the resurrection of Jesus in a recitative and continues in an aria, both accompanied only by the continuo. The aria, marked "Molto adagio", praises Jesus as "Prince of life" and "strong fighter". The higher tenor voice addresses in a recitative the soul to look to the "new life in spirit", followed by a bright aria, accompanied by the strings, which speaks  of "" (the new man), free from sin. The highest voice, the soprano, sings in the first person as the soul in a recitative, convinced of taking part in the resurrection. In the last aria, soprano and solo oboe in echo-effects contrast with low-lying unison strings, which already anticipate the closing chorale's melody. The hymn is a "death-bed chorale", set for a four-part choir, crowned by a descant from the trumpet and first violin.
