The cantata begins in
B minor, illustrating sorrow, but in movement 4 shifts to the relative major key of
D major, illustrating the theme of consolation in Ziegler's text. The opening chorus has an unusual structure, which includes an
arioso passage for the bass voice. All instruments except the trumpet play a
ritornello, after which a choral
fugue pictures the weeping and wailing of the text in unrelated musical material, rich in
chromaticism. In great contrast the following line, "" (But the world will rejoice), is conveyed by the chorus embedded in a repeat of the first part of the ritornello. The sequence is repeated on a larger scale: this time the fugue renders both lines of the text as a double fugue with the second
theme taken from the ritornello, then the ritornello is repeated in its entirety. The bass as the
vox Christi (voice of Christ) sings three times, with a sudden tempo change to
adagio, "" (But you will be sad) as an accompagnato recitative. Musicologist Julian Mincham noted: "This recitative is a mere eight bars long but its context and piteousness give it enormous dramatic impact. Bach's lack of respect for the conservative Leipzig authorities' dislike of operatic styles in religious music was never more apparent!"
Klaus Hofmann compares the recitative's "highly expressive melody and harmony" to Bach's
Passions. Finally, the extended sequence of fugue and ritornello with chorus returns transposed, on the text "" (Yet your sorrow shall be changed into joy). According to
Alfred Dürr, the architecture of the movement is a large scale experiment combining elements of the older style of a text-related
motet with the form of a concerto of instrumental groups and voices, as typically used by Bach.
John Eliot Gardiner, who conducted the
Bach Cantata Pilgrimage with the Monteverdi Choir in 2000, notes that Bach's "strategy is to superimpose these opposite moods, binding them in a mutually enlightening whole and emphasising that it is the same God who both dispenses and then ameliorates these conditions. Movement 2 is a secco recitative for tenor, concluding in an arioso section with a "deeply moving"
melisma on the word "" (sorrows). Movement 3, "" (Besides You is no doctor to be found) is an
aria for alto with the
obbligato flauto piccolo, which according to Mincham, employing a "figuration ever striving upwards, moderates the underlying sense of potential tragedy". The alto recitative "marks a change of scene", it begins in B minor, like the opening chorus, but modulates to D-major and ends with a wide-ranging
coloratura marking the word "" (joy). Movement 5, "" (Recover now, O troubled feelings), picks up the joyful coloraturas, supported by the trumpet and fanfares in
triads in the orchestra; Mincham notes that the trumpet "bursts upon us with an energy, acclamation and jubilation unheard, so far, in this work". The cantata is closed with a four-part setting of the
chorale, sung to the melody of "" which Bach used frequently, including in his
St Matthew Passion. == Recordings ==
