German: O ewiges Feuer, o Ursprung der Liebe (O eternal fire, o source of love),[1] 34 (BWV34.1), is a church cantata by Johann Sebastian Bach. He composed it in Leipzig for Pentecost Sunday, and it was the basis for a later wedding cantata, BWV 34a, beginning with the same line. Bach led the first performance on 1 June 1727.[2]
The librettist of the cantata is unknown. A central contemplative aria for alto, accompanied by two flutes and muted strings, is framed by recitatives, while the two outer movements are performed by the chorus and a festive Baroque instrumental ensemble of three trumpets, timpani, two oboes, strings and continuo. The last movement quotes the conclusion of Psalm 128, "German: Friede über Israel|italic=no" (Peace upon Israel). The themes of eternal fire, love, dwelling together and peace suit both occasions, wedding and Pentecost.
Bach adapted movements 1, 3 and 5 of this cantata for Pentecost Sunday in a later wedding cantata, German: [[O ewiges Feuer, o Ursprung der Liebe, BWV 34a|''O ewiges Feuer, o Ursprung der Liebe'', BWV 34a]] |italic=unset. Formerly it was believed that BWV34a (as BWV34.2 was then called) was the older work.[3] In Bach's Leipzig, the readings for Pentecost were from the Acts of the Apostles, on the Holy Spirit, and from the Gospel of John, in which Jesus announces the Spirit who will teach, in his Farewell Discourse .[4] The workload of the composer and his musicians was high for Christmas, Easter and Pentecost, because in Leipzig they were all celebrated for three days.[5] The texts are of unknown authorship.[6] [7] The beginning of the text of the wedding cantata could be kept unchanged, because the image of the flames and the spirit of love suit the Pentecostal events as well as a wedding: the author had only to replace the reference to "vereinigtes Paar" (united couple) with a reference to the gospel. Movement 5 quotes the conclusion of Psalm 128, "German: Friede über Israel|italic=no" (Peace upon Israel,). This quote was already part of movement 4 of the wedding cantata, which quotes in movement 3 verses 4–6a from the same psalm.[8]
Bach led the first performance on 1 June 1727 in the Nikolaikirche. The Bach scholar Klaus Hofmann notes that a printed libretto for the congregation was recently found in the Russian National Library in St. Petersburg, containing the texts for the three feast days of Pentecost and Trinity of 1727. Until then the work had been dated much later, such as 1746 when a revival took place for which performance material exists. As the music of the 1727 version is lost, the timing of Bach's revisions to the wedding cantata is not known. It is likely that he revised it further in the 1740s because he wrote a new score.
Bach structured the cantata in five movements, with two choral movements framing a sequence of recitative–aria–recitative. Bach scored the work for three vocal soloists (alto, tenor, bass), a four-part choir and a Baroque instrumental ensemble of three trumpets (Tr), timpani (Ti), two flauti traversi (Ft), two oboes (Ob), two violins (Vl), viola (Va) and basso continuo.[9] The Bach scholar Christoph Wolff describes the "large-scale instrumental scoring" as "suited to the festive occasion".
In the following table of the movements, the scoring follows the Neue Bach-Ausgabe. The continuo, playing throughout, is not shown.
The opening chorus, "German: O ewiges Feuer, o Ursprung der Liebe|italic=no" (O eternal fire, o source of love), illustrates two contrasting subjects, "ewig" (eternal) and "Feuer" (fire). While "ewig" appears as long notes, held for more than one measure, the flames (or tongues) of the fire are set in "lively figuration from the strings and agile coloraturas from the voices".[10] The instrumental ritornello comprises a sustained trumpet entry, active strings, and "flickering" oboes, drums, and trumpets. Unlike in most da capo movements, this ritornello appears only at the beginning and end.[11] The basses enter first, "holding a top D for most of five bars to symbolise the 'eternal', the other three parts aglitter with 'fiery' embellishments", as John Eliot Gardiner notes. The middle section develops these themes in minor keys, in "dance-like vocal pairings", before the ritornello returns one more time to reprise the first section.
A tenor recitative, "German: Herr, unsre Herzen halten dir dein Wort der Wahrheit für|italic=no" (Lord, our hearts keep Your word of truth fast), adopts an authoritative tone, is in minor mode, and begins with a bass pedal. It expands the concept of God abiding with his people, as outlined in the gospel.
An alto aria, "German: Wohl euch, ihr auserwählten Seelen, die Gott zur Wohnung ausersehn|italic=no" (It is well for you, you chosen souls, whom God has designated for his dwelling), conveys images of contentment by incorporating a lilting berceuse-like rhythm, with an obbligato melody played by muted violins and flutes in octaves and tenths. It is accompanied by a tonic pedal in the continuo. The aria is in adapted ternary form. The pastoral character suited the original text, "Wohl euch, ihr auserwählten Schafe" (It is well for you, you chosen sheep), which alludes to the bridegroom, a pastor or "shepherd of souls". Gardiner notes "the tender sensuousness of the pastoral writing, the pairings of thirds and sixths, the blending of flutes and muted strings and the satisfying textures and calm enchantment disturbed only momentarily by modulation", and considers that the piece possibly had some "deeper personal significance".
The bass recitative, "German: Erwählt sich Gott die heilgen Hütten, die er mit Heil bewohnt|italic=no" (If God chooses the holy dwellings that He inhabits with salvation), is quite similar in character to the tenor recitative. The last two measures form an introduction to the closing movement.
The closing chorus, "German: Friede über Israel|italic=no" (Peace upon Israel), opens with a solemn rendering of the psalm text, marked Adagio. The violins and oboes first play an ascending figure. Gardiner notes that the section is "reminiscent of and equivalent in grandeur to the opening exordium to the B minor Mass". The slow music on the psalm text is contrasted by a "spirited and very secular-sounding march, setting "German: Dankt den höchsten Wunderhänden|italic=no" (Thank the exalted wondrous hands). Both sections appear first as instrumental and are then repeated by the chorus. Hofmann notes that this music is reminiscent of Bach's works for the Köthen court, composed for Leopold, Prince of Anhalt-Köthen. Gardiner concludes:
