The cantata is unique in Bach's church cantatas in its structure of arias combined with chorale instead of recitatives. Performed one week after , it shows Bach's emphasis on the chorale even beyond his second cycle of
chorale cantatas, begun in 1724. The opening chorus is opened by a
ritornello, dominated by two contrasting
motifs: the strings play a short rising figure in triplets, the oboes d'amore play an expansive melody. As in the secular model, the movement is in two similar parts, each consisting of two contrasting sections, "" (Soar joyfully upwards to the exalted stars) and "" (Yet stop!). The bass voice, the lowest register, enters first, followed by the tenors, altos, and sopranos. This ascending sequence also reflects the text: "soaring aloft", literally "swinging upward". Gardiner, who conducted the three cantatas for the first Sunday in Advent during the
Bach Cantata Pilgrimage with the Monteverdi Choir in 2000, described the movement as a "spiritual madrigal – capricious, light-textured and deeply satisfying once all its virtuosic technical demands have been met: those tricky runs, divisions and chromatic intervals in all voices, and the chains of triplet figuration in the unison oboes d'amore and first violins". He compares the figures on "" (stop) in the middle section to "" (where) in the aria "" in Bach's
St John Passion. All three settings of the stanzas from Luther's chorale are different, beginning with a
duet for soprano and alto for the first stanza. The voices are doubled by the oboes d'amore and render the text in sections of different length, with sixteen measures for the final "" (that God had ordained such a birth for Him).
Alfred Dürr notes the expressiveness of the music, especially in leaps of
sixths on the urgent request "" (now come), syncopated rhythm on "" (over whom the whole world marvels), and daring
chromatic on the final line. The tenor aria reflects "" (Love approaches with gentle steps) with oboe d'amore as
obbligato instrument, "the traditional musical symbol of love", alluding to the concept of Jesus as the bride-groom and the Soul as the bride, which is also the base for Nicolai's hymn that closes part I in a "rousing four-part harmonisation". The bass aria beginning part II, "" (Welcome, worthy treasure!) shows "echoes of the first movement" and avoids a regular
da capo structure. The bass voice is the
vox Christi, addressing the bride. The welcoming gesture from the secular cantata seems appropriate for the expressed sentiment. The next hymn stanza, "" (You who are like the Father), the sixth stanza from Luther's hymn "dealing with the sins of the flesh and Christ's mission to redeem humankind", is marked "molt' allegro". The tenor sings the chorale melody unadorned as a
cantus firmus, but the oboes d'amore play with "the urgent surging of semi-quaver activity". Dürr sees the expression of "" (fight and victory of the Son of God) over "" (weak/sick flesh) of man. Gardiner compares it to a trio sonata movement. He terms the last aria "a
berceuse of pure enchantment" and compares it to the "echo aria" from part IV of Bach's
Christmas Oratorio. The text "" (Also with muted, weak voices) is illustrated by a muted (
con sordino) solo violin. The closing choral, the final stanza of Luther's hymn, "" (Praise be to God, the Father) is a four-part setting. \header { tagline = ##f } \layout { indent = 0 \context { \Score \remove "Bar_number_engraver" } } global = { \key b \minor \time 4/4 } soprano = \relative c'' { \global \set Staff.midiPanPosition = -0.5 \set midiInstrument = "violin" b4 b a d | cis8 (b) cis4 b2\fermata | b8 (cis) d4 e d | e fis d2\fermata | d4 e fis8 (e) d4 | e8 (d) cis4 b2\fermata | b4 b a d | cis8 (b) cis4 b2\fermata \bar "|." } alto = \relative c' { \global \set Staff.midiPanPosition = 0.5 \set midiInstrument = "violin" fis4 e fis fis8 g16 a | g8 fis e4 d2 | fis4 fis8 gis a4 a8 b | cis4 d8 fis, g!2 | a4 a a8 ais b4 | cis8 b ais4 fis2 | fis4 eis fis8 [gis] a b | fis8 b4 ais8 fis2 \bar "|." } tenor = \relative c' { \global \set Staff.midiPanPosition = -1 \set midiInstrument = "cello" d4 cis8 b cis4 b | b4. ais8 fis2 | d'8 cis b4 cis d | g, a!8 b16 c b2 | a4 e' d8 cis b4 | g' cis,8 fis d2 | d4 cis8 b cis4 fis | e8 d cis16 d e8 dis2 \bar "|." } bass = \relative c { \global \set Staff.midiPanPosition = 1 \set midiInstrument = "cello" b'8 a g4 fis8 [cis8] d b | e [d] e fis b,2 | b4 b' a8 g fis4 | e d g2 | fis8 [e] d cis d4 g8 fis | e4 fis b,2 | b'8 a eis4 fis8 [e] fis g | ais b fis4 b,2 \bar "|." } verse = \lyricmode { Lob sei Gott, dem Va -- ter, g'ton, Lob sei Gott, sein'm ein -- gen Sohn, Lob sei Gott, dem Heil -- gen Geist, im -- mer und in E -- wig -- keit! } \score { \new ChoirStaff > \new Lyrics \with { \override VerticalAxisGroup #'staff-affinity = #CENTER } \lyricsto "soprano" \verse \new Staff > >> \layout { } } \score { \midi { \tempo 4=96 \context { \Score midiChannelMapping = #'instrument } \context { \Staff \remove "Staff_performer" } \context { \Voice \consists "Staff_performer" } } { > } } == Recordings ==
