BWV 34 - O ewiges Feuer, o Ursprung der Liebe

Week 34 (17 September – 28 December 2013)

Recording: Rudolf Lutz, Vokalensemble/Instrumentalensemble der Schola Seconda Pratica; Margot Oitzinger, alto; Jens Weber, tenor; Fabrice Hayoz, bass


Yes, that was a mighty long week. But I have managed at last to escape the eternal fire-fighting that is my life to write about Bach’s eternal fires, both sacred and secular. The cantata is certainly not at fault for my tardiness: it’s a lovely work, and I have spent many hours in the company of both the full recording as well as multiple versions of the very special alto aria that, as the linch-pin of the piece, “helps to convey a special color and unity to the whole,” as Sir Hubert Parry describes.
The choral movements and aria derive from an earlier Leipzig wedding cantata, BWV 34a, which bears the same title since it uses the identical opening lines. The work, which does not survive in complete score, must have been composed for a notable marriage, perhaps for a member of the clergy as suggested by the recitative text Dir, dessen Fleiss in Gottes Hause wacht. Certainly the prominence of brass and percussion, as well as full chorus and four soloists, indicates that the event was one with “no expense spared”.
BWV 34 was subsequently assembled to provide music for another festive occasion, Pentecost, or the “birthday of the church”. Recent research cited in the liner notes for Suzuki’s recording indicates that the shorter, sacred version was first performed in 1727, with subsequent use as late as 1740, from which time the surviving manuscripts date.
The brilliant opening chorus evokes divine flames of virtuous love and faith – the ardor of the faithful – first with an instrumental prelude of rising and falling surges of strings and brass, then with the fugal 4-part choral setting depicting both the immensity of eternity and the dancing fire. Note the little syncopation on entzünde (ignite) that leads off the B section – not one detail is ever glossed over. This is an immensely rewarding choral movement, although the da segno form makes it long for use as an anthem, the A section stands on its own – for a nimble and energetic choir that can survive the melismatic flames. Lutz’s performance for the Bach-Stiftung sparkles, with the vocal parts clearly delineated in a warm acoustic.
In adapting his earlier work for Pentecost, Bach was provided (either by his own hand or by an unknown writer) a text focusing on the soul becoming the selected dwelling place of God. This idea of being chosen is emphasized through use of the word erwählen and its derivatives in the recitatives and aria. Note the repetitions in the alto aria (five in the A section alone) of auserwählten (literally, picked out from a larger group).
The magnificent Wohl euch, ihr auserwählten Seelen is surely one of the most beautiful alto arias in the cantatas. Bach reused the music from the earlier BWV 34a; however, in that work the text references the Biblical love story of Jacob and Rachel. John Eliot Gardiner suggests this music “may have had deeper personal significance to Bach than we can fathom today”, but he sagely withholds any further inferences. The meltingly tender melody and the manner in which the singer directly addresses the audience (congregation) bespeak sincere affection. The instrumental setting using two flutes and strings envelops the singer in warmth, and the vocal line must be equally buoyant and ethereal, particularly in the first section of the aria.
In the printed key (A major), the aria is appropriate for lighter altos and lower sopranos who can easily sing a B4 without any chest tone. In order to achieve the necessary ease and fluidity, there has first to be technical mastery, and this aria offers an abundance of challenges that develop and improve vocal technique. One difficult aspect for a female alto is the constant crossing of the lower and middle breaks, which can make achieving a blended sound difficult. Several excellent exercises can be extracted from the aria to facilitate this process, e.g. M. 20-22.
Although rather long (about 6 minutes) for use as a church service selection, the aria’s A-B-A’ structure permits using the last section in that capacity. It’s such a beautiful aria that it should be shared with your listeners even if that must be in an abbreviated form. But by reverting to the original text, what a perfect piece for a wedding (if anyone out there is still asking for Bach)! The original BWV 34a version opened the second portion of the cantata (Post copulationem), and apparently used only violin and continuo for accompaniment, making for a very natural adaptation for voice and organ. The music is available in the Breitkopf and Härtel edition of 1894 (on IMSLP).
Margot Oitzinger’s performance in BWV 34 (also available as a video clip on YouTube) is a wonderful example of a fresh, warm sound with naturally minimal vibrato that nevertheless maintains exceptional intonation. But do not neglect the recording by Janet Baker, which shows how a larger, weightier voice, when managed well, can produce the effortless quality needed in this aria.
A bass recitative summons the adagio choral declaration Friede über Israel, from which flows out the closing chorus of thanks. In an extraordinary passage resolving the brief contrapuntal opening, all four voices repeat dankt in emphatic unison (in the secular version, where this music concludes the first portion of the cantata prior to the sermon, the motif belongs to the word eilt). An instrumental interlude provides more celebratory touches before a short B section and recapitulation.
Given the opulence of the writing in the two surviving choral movements, it’s reasonable to assume that the lost final chorus of BWV 34a was probably something of a tour de force. The 1894 B&H full score includes the extant soprano and bass parts together with fragmentary strings and continuo parts, with the empty alto and tenor staves taunting you in their blankness. The manuscript alto part bears only a blank page where this music should have been – in the flurry to complete all the parts for the performance, the alto and tenor lines must have been written out on separate sheets that disappeared. If I could have some lost pieces found, it would be the other parts for this chorus, whose text alternates the famous benediction from Numbers 6 (May the Lord bless you and keep you) with other words of blessing, and concludes in a long sequence of Amens. A complete BWV 34a would be a significant addition to the repertoire.
Some time has passed and I’m behind in this project, but that was probably inevitable given the scope of the task as well as my hectic schedule. Among other events has come in October the publication of John Eliot Gardiner’s Bach book, Music in the Castle of Heaven. As I have worked through this first year and utilized so many of Sir John’s liner notes from his Cantata Pilgrimage journals, I found myself hoping that somehow these journals would be collected and published separately. And here they are! Well, perhaps not in their entirety, but much of that material has been incorporated here, along with a lifetime’s experience studying, performing, and living this repertoire. If you still owe a musician a Christmas present, here it is.
