Structure and scoring Bach structured the cantata in six movements, beginning with a biblical quotation for the
vox Christi, Jesus speaking. A set of aria and recitative is followed by a chorus on another biblical quotation from the gospel, while an aria leads to the closing chorale. Bach scored the work for three vocal soloists (
alto (A),
tenor (T) and
bass (B)), a
four-part choir, and a
Baroque instrumental ensemble of two
oboes d'amore (Oa), two
violins (Vl),
viola (Va) and
basso continuo. The duration of the cantata is given as 20 minutes. In the following table of the movements, the scoring follows the
Neue Bach-Ausgabe. The
keys and
time signatures are taken from
Alfred Dürr, using the symbol for common time (4/4). The continuo, playing throughout, is not shown.
Movements The cantata presents similarities to the one Bach wrote the previous year for the same occasion, .
1 The similarities begin with the first movement, which like that of the previous year's cantata, is given to the bass as the
vox Christi. The movement is the quotation of verse 7 from the gospel, beginning: "" (It is good for you that I leave; for if I did not go, the Comforter would not come to you). It is between
aria and
arioso. An oboe d'amore as the
obbligato instrument plays extended melodies. Voice and oboe share the musical material, conveying "the mood of grieving at parting".
2 The following aria, "" (No doubt can disturb me), is dominated by a virtuoso solo violin. The words "Ich glaube" (I believe) are illustrated by very long notes in the voice, while an
ostinato bass line renders "steadfastness" in a different way. The musicologist Julian Mincham notes that Bach uses the key F-sharp minor selectively, "often for slowish movements of great expressive force", for example for the alto aria
Buß und Reu from his St Matthew Passion.
3 A short secco
recitative expresses "" (Thus Your Spirit will guide me, so that I walk on the right path).
4 The next biblical quotation, verse 13 of the gospel, "" (But when that one, the Spirit of Truth, shall come, He shall lead you into all truth). is rendered by the choir. It is divided in three sections, similar to a
da capo form. All three parts are
fugues, combined in motet style, the instruments playing mostly
colla parte with the voices. The second section begins "" (For He will not speak of His own accord); the third section expresses "" (and what is to come, He will foretell), on a fugue subject similar to the first, giving the movement a "feeling of unity".
5 The last aria,"" (What my heart desires from You), is accompanied by the strings, dominated by the first violin. The word "Herz" (heart) is rendered in sighing
motifs, intensified by following rests.
6 The closing chorale, "" (Your Spirit, which God sends from heaven, leads everything that loves Him), is a four-part setting on the melody of "". The bass line is pacing forward constantly. == Recordings ==
