Scoring and structure The title on the copy by Johann Christian Köpping is: "Concerto a 2 Violi:1 Viola. Fagotto Violoncello S.A.T.e Basso e Continuo / di Joh:Seb:Bach" (Concerto for 2 violins, 1 viola. Bassoon Cello S.A.T and Bass and Continuo / by Joh:Seb:Bach). The cantata in six movements is scored like
chamber music for four vocal soloists (
soprano,
alto,
tenor and
bass), a
four-part choir (SATB) in the closing chorale, two
violins (Vl),
viola (Va),
bassoon (Fg),
cello (Vc) and
basso continuo (Bc). The bassoon is called for, but has no independent part. The duration is given as about 15 minutes. In the following table of the movements, the scoring follows the Neue Bach-Ausgabe, and the abbreviations for voices and instruments the
list of Bach cantatas. The
keys and
time signatures are taken from the Bach scholar
Alfred Dürr, using the symbol for common time (4/4). The instruments are shown separately for winds and strings, while the continuo, playing throughout, is not shown.
Movements The cantata consists of solo movements closed by a four-part chorale. Arias alternate with two recitatives, both sung by the bass.
John Eliot Gardiner summarizes: "It is a true sermon in music, based on the Gospel account of Jesus' night-time conversation with Nicodemus on the subject of 'new life', emphasising the spiritual importance of baptism." He points out the many musical images of water.
1 In the first aria, "" (O bath of Holy Spirit and of water), the
ritornello is a
fugue, whereas in the five vocal sections the soprano and violin I are a duo in imitation on the same material. These sections are composed in
symmetry, A B C B' A'. The theme of B involves an
inversion of material from A, that of C is derived from measure 2 of the ritornello. Dürr writes:
2 The first recitative, "" (The sinful birth of the cursed heirs of Adam), is
secco, but several phrases are close to an
arioso. The musicologist Julian Mincham notes that Bach follows the meaning of the text closely, for example by "rhythmic dislocations for death and destruction", a change in harmony on "poisoned", and "the complete change of mood at the mention of the blessed Christian". He summarizes: "Here anger and resentment at Man’s inheritance of suppurating sin is contrasted against the peace and joy of God-given salvation".
3 The second aria, "" (Jesus, who out of great love), accompanied by the continuo, is dominated by an expressive
motif with several upward leaps of
sixths, which is introduced in the ritornello and picked up by the alto voice in four sections. Mincham notes that "the mood is serious and reflective but also purposeful and quietly resolute".
4 The second recitative, "" (I have indeed, o bridegroom of my soul), is accompanied by the strings (
accompagnato), marked by Bach "Rec: con Stroment" (Recitative: with instruments). The German musicologist
Klaus Hofmann notes that the text turns to mysticism, reflecting the Bridegroom, Lamb of God and the serpent in its double meaning. The text is intensified by several
melismas, a marking "
adagio" on the words "" (most holy Lamb of God), and by melodic parts for the instruments. Gardiner notes that Bach has images for the
serpent displayed in the desert by
Moses, and has the accompaniment fade away on the last line "" (when all my strength has faded).
5 The last aria, "" (Jesus, death of my death), is set for tenor, accompanied by the violins in
unison, marked "Aria Violini unisoni e Tenore". The image of the serpent appears again, described by the composer and musicologist
William G. Whittaker: "the whole of the
obbligato for violins in unison is constructed out of the image of the bending, writhing, twisting reptile, usually a symbol of horror, but in Bach's musical speech a thing of pellucid beauty".
6 , who wrote the hymn tune The cantata closes with a four-part setting of the chorale stanza, (His word, His baptism, His communion). The text in four short lines summarizes that Jesus helps any in need by his words, his baptism and his communion, and ends in the prayer that the Holy Spirit may teach to faithfully trust in this. The hymn tune by
Nikolaus Selnecker was first published in Leipzig in 1587 in the hymnal
Christliche Psalmen, Lieder vnd Kirchengesenge (Christian psalms, songs and church chants). Bach marked the movement: "", indicating that the instruments play with the voices. == Recordings ==
