Structure and scoring Bach structured the cantata in six even movements. The chorale tune is used in the outer choral movements, a
chorale fantasia and a four-part closing chorale. The inner movements are alternating recitatives and arias. Bach scored the work for four vocal soloists (
soprano (S),
alto (A),
tenor (T) and
bass (B)), a
four-part choir, a
four-part choir, and a festive
Baroque instrumental ensemble of three
trumpets (Tr),
timpani,
flauto traverso (Ft), three
oboes (Ob), two
violins (Vl),
viola (Va), and
basso continuo. In the following table of the movements, the
keys and
time signatures are taken from the Bach scholar
Alfred Dürr, using the symbol for
common time. The instruments are shown separately for brass, woodwinds and strings, while the continuo, playing throughout, is not shown.
Movements 1 In the opening chorus, (Lord God, we all praise you ... for your creation of the beautiful angels), Bach illustrates the singing of angels in different choirs by assigning different
themes to the strings, the oboes and the trumpets, in a rich scoring typical only for the most festive occasions of the liturgical year such as Christmas. Mincham compares the movement to the 15 opening movements preceding it in the second annual cycle: "It is the most lavishly scored chorus so far and certainly the most extrovertly festive in character".
2 A recitative for alto, (Their brilliant radiance and exalted wisdom shows how God bends himself down to us humans), is set
secco. Two lines from the original chorale are retained.
3 A bass aria, (The old dragon burns with envy), is unusually scored for only trumpets, timpani and continuo, describing the battle of the angels against Satan.
4 A duet recitative of soprano and tenor, (But it is fortunate for us, who day and night are guarded by the throng of angels), recalls guardian angels saving Daniel in the lions' den and the three men in the furnace.
5 An aria for tenor, (Allow, O Prince of the cherubim, ),
John Eliot Gardiner, who conducted the
Bach Cantata Pilgrimage in 2000, compared the flute line in a
gavotte for tenor to "perhaps the fleetness of angelic transport on Elijah's chariot", which is mentioned in the text.
6 The closing chorale, (Therefore, we rightly praise you), is a four-part setting of the 11th hymn stanza that includes again "the angelic trumpets". Bach had intended to set also the 12th stanza, but he crossed it out in the score, and the extant parts only have the 11th stanzas's text. \header { tagline = " " } \layout { indent = 0 \context { \Score \remove "Bar_number_engraver" } } global = { \key c \major \numericTimeSignature \time 3/4 \set Score.tempoHideNote = ##t \set Timing.beamExceptions = #'()} su = \once { \stemUp \omit Beam \override NoteColumn.ignore-collision = ##t } sd = \once { \stemDown \override NoteColumn.ignore-collision = ##t } \score { > \new ChoirStaff > \new Lyrics \lyricsto "soprano" { Da -- rum wir bil -- lig lo -- ben dich und dan -- ken dir, Gott, e -- wig lich, wie auch der lie -- ben En -- gel Schar dich prei -- _ sen heut _ und im -- mer -- dar. } \new Staff > >> \new Staff \with { \magnifyStaff #5/7 } > >> \layout { \context { \Score \remove "Mark_engraver" \remove "Staff_collecting_engraver" } \context { \Staff \consists "Mark_engraver" \consists "Staff_collecting_engraver" } } } \score { > \new ChoirStaff > \new Staff \with { midiInstrument = "choir aahs" } > >> \new Staff \with { midiInstrument = "timpani" } > >> \midi { } } == Manuscripts and publication ==
