Structure and scoring Bach structured the cantata in eleven movements, in two parts. The outer movements—the opening chorus and the closing chorale—are sung by the choir, and frame a sequence of alternating recitatives and arias. The work is scored for four vocal soloists (
soprano (S),
alto (A),
tenor (T),
bass (B)), a
four-part choir and a festive
Baroque instrumental ensemble of three trumpets (Tr) and
timpani (Ti), two
oboes (Ob), two
violins (Vl),
viola (Va), and
basso continuo.
Alfred Dürr noted in his book that this scoring is almost as opulent as for the later
Ascension Oratorio. The title page of the original parts reads: "Festo Ascens. Xsti. / Gott fähret auf mit Jauchzen / a / 4 Voci / & Trombe / Tamburi / & Hautb. / & Viol. / Viola / e / Cont. / di / J. S. Bach", which means "Feast of the Ascension of Christ / Gott fähret auf mit Jauchzen / for 4 voices, & trumpets, timpani, & oboes, violins, viola, & continuo, by J. S. Bach". Dürr gave the duration as 25 minutes. In the following table, the scoring follows the . The
keys and
time signatures are taken from Dürr, using the symbols for
common time (4/4) and (2/2). The continuo, playing throughout, is not shown.
Movements The cantata begins with an imposing opening chorus, which, as in Bach's
Orchestral suites, nothing that follows can balance. Due to the long text, the work unusually features short arias and five recitatives, most of them
secco, with the exception of the one beginning Part II. Dürr believes that Bach may have taken not only his cousin's text format but also his music-making as a model.
1 The opening chorus, "" (God goes up with jubilation and the Lord with bright trumpets) with the full orchestra, is the "centre of gravity" of the cantata. It opens with an introduction marked "
adagio", played by the strings doubled by the oboes. Then a
fugue begins, two instrumental entries are followed by choral entries, and a climax is reached in an entry of the first trumpet. A second fugue includes remote and minor keys. The second part of the text, "" (sing praises to God, sing praises unto our King) is first sung in
homophony, but then presented in a third fugue on the theme of the first, followed by a homophonic
coda.
2 A secco recitative for the tenor, "" (The Highest prepares for himself a triumphal procession), expresses that God makes the prisons captives, in syllabic declamation.
3 In the first aria, "" (Indeed thousand upon thousands accompany the chariots), the tenor is accompanied by the violins in
unison. The complete text is sung three times in different sections.
Hans-Joachim Schulze notes that the "energetic repeated pitches, spacious broken chords, and sweeping passages" give the aria a heroic character, although the triple meter might indicate a dance type.
4 The New Testament quotation about the Ascension, "" (And the Lord, after he had spoken with them, was taken up into heaven and sits at the right hand of God.), is sung not by the tenor as the
Evangelist, but instead the soprano narrates it in a secco recitative.
5 The fifth movement concludes Part I and is based on the first stanza of the poem, "" (My Jesus has now completed the work of salvation). The soprano is accompanied by the strings which are doubled by the oboes. In the middle section, the words "" (He finishes His course on earth, literally: "He finishes the course of the earth") are expressed by an upward
melisma and one downward on the repeat of the words. Schulze characterises the aria as introverted and sympathetic.
6 The recitative, "" (The hero of heroes comes, the terror and bane of Satan,), is sung by the bass. In the strings,
triadic fanfares alternate with soft
tremolo, illustrating the drama of the text with contrasting aspects of power and anxiousness.
7 The bass continues in an aria, "" (It is he, who completely alone has trod upon the winepress). It is highlighted by an
obbligato trumpet part, which Schulze saw as a symbol of the "solitariness of the victor". The trumpet part is so difficult that Bach gave it to a violin in a later performance. Repeated figures in the continuo may illustrate the treading in the winepress. The words "" (full of sorrow, torment and pain) are illustrated by a slower tempo and harmonic tension.
8 In this recitative for the alto, "" (The Father has indeed ordained for him an eternal Kingdom), the vocal line concludes with a reference to the view towards heaven, expressed by an upward
coloratura motion.
9 The alto aria, "" (I see already in spirit, how he, at God's right hand, smites his enemies). is accompanied by the oboes. It expresses the joy of victory over the enemies, in a dance-like vision of peace rather than a description of a battle, but stresses the words "" (out of suffering, distress and ignominy) by "harmonic darkening". Schulze notes that in the second Part, like in the first, a tranquil aria follows one full of tension, here ignoring aspects of the text.
10 A soprano recitative, "" (He will prepare next to him a dwelling-place for me), expresses a vision of a heavenly dwelling.
11 The closing chorale in two stanzas, "" (O Prince of Life, Lord Jesus Christ), is a four-part setting of the melody of "", composed by
Johann Schop in 1641. The chorale setting was not composed by Bach, but he took it from the 1682 '''' hymnal by
Gottfried Vopelius, with only slight alterations. The oldest source for the hymn, the 1655 collection (Devotional cymbals) by , cantor in
Guben, was not at Bach's disposal. The instruments play with the voices, according to the parts two trumpets, the oboes and two violins with the soprano, and one trumpet and viola with the alto. Michael Märker, the editor of a critical edition for
Carus-Verlag, notes that the soprano and alto lines were too low for trumpets to play along, and that Dürr suggested that trumpeters played violins for that movement. == Manuscripts and publication ==
