Structure and scoring Bach structured the cantata in six movements, beginning with a duet, followed by a series of alternating recitatives and arias and concluded by a chorale. Similar to several other cantatas on words by Franck, it is scored for a small ensemble: four vocal soloists (
soprano (S),
alto (A),
tenor (T) and
bass (B)),
oboe (Ob), two
violins (Vl),
viola (Va), and
basso continuo (Bc) including
bassoon (Fg). A choir is only needed for the chorale, if at all. The score, partly an
autograph, is titled "Concerto. / Dominica post Trinit: / Brmhertziges Hertze der ewigen Liebe. ect. / â 5 Strom. 4 Voci / Tromba / 1 Hautb 2 Violini. 1 Viola. / Violoncello / è Fagotto. S. A. T. è Baßo con Cont. / di JSbach. / 1715", while "tromba" (trumpet) is struck in the cover of the set of parts. In Leipzig the oboe was replaced by a
clarino (trumpet) for the instrumental
cantus firmus of the chorale in the first
movement. The duration is given as 16 minutes. In the following table of the movements, the scoring and
keys are given for the version performed in Weimar in 1714. 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 1 The opening movement is a duet of soprano and tenor, "" (Compassionate heart of eternal love). It is in two ways connected to the chorale which closes the work. The melody is played line by line as a by the oboe, embellished and in a dancing 6/4 time instead of 4/4. The first interval in the voices and the continuo is the same as in the chorale. The
countersubject is the
inversion of the theme, in German "" (reflection in a mirror). It reflects the theme as human mercy should reflect divine mercy.
John Eliot Gardiner, who conducted the
Bach Cantata Pilgrimage with the Monteverdi Choir in 2000, comments in his diary of the project: "Cast as a
siciliano for soprano and tenor with cello continuo, there is a warm glow to this opening duet, with trills on each of the main beats to signify the flickering flame of love, and a plea to 'come melt my heart'. Agricola's chorale tune [...] is meanwhile intoned by a clarino hovering above the two amorous vocal lines.
2 The alto recitative, "" (You hearts, which have changed yourselves into rocks and stones), is first accompanied by the strings, but ends as an
arioso with continuo.
3 The alto aria, "" (Be inspired at the present time) shows the richest instrumentation, with figurative oboe solos.
4 The bass recitative "" (Self-love flatters itself!) is accompanied only by the continuo.
5 The text of the bass aria with continuo, "" (This is the Christian's art), summarizes all injunctions in one long sentence, but Bach splits it in parts, all introduced by the keywords "". The bass as the (voice of Christ) delivers the "sermon". In Leipzig, the continuo of cello and bass in octaves was doubled by the strings, another octave higher. Gardiner admires Bach's treatment as a "gentle, parodistic way he portrays the rhetorical displays of a pompous preacher".
6 The closing chorale, "" (I call to You, Lord Jesus Christ), summarizes the topic of the cantata to love and serve the neighbour. It is illuminated by a "soaring" violin as a fifth part, similar to the treatment in the cantata for Pentecost the previous year, .
Reception The musicologist Isoyama summarizes: "... we are bound to admire the emotional wealth with which Bach's music infuses the poetry. In that it gives living reality to a potentially dry text, this work may be numbered among Bach's masterpieces". == Recordings ==
