We have recorded almost everything now - there are only about twelve cantatas left. We were talking for quite a bit of time with some of the major record companies, but none of them had the money or the guts to do it. For the last 8 months we were in negotiations with Andante, a company that specialises in marketing music on the internet and wanted to establish a record label. We agreed that they would issue the recordings, though we were not to publish their name in advance. That was at the end of July, but we later decided that we wouldn’t do it with them. We are going to do it ourselves, establishing our own label for the Bach cantatas - and maybe other things as well - together with Challenge Classics. We are aiming to release volume 13 by early March, and continue at the rate of three volumes a year. I now also own the tapes of the Bach cantatas that were previously released by Erato, so these older volumes, numbers 1-12, will be published with the same label, one per month. The label will be called Antoine Marchand, which is the French for my name, Ton Koopman. It will have different distributors in different countries. We have already been working on the designs of the album covers.

So the aim is for volume 13 to come out by the beginning of March, vol. 14 in the middle of the year and vol. 15 in December 2003 or January 2004. We have been negotiating with the distributors about the order of releasing the previous volumes - whether we would start with volume 1, or go backwards from volume 12. Volumes 11 and 12 have only been available for a very short time; so my preference would be to start by re-issuing these newer volumes, and work backwards towards the beginning. We have yet to make the final decision on this; but the one positive decision we already made is to re-release them all within 12 months, and make the entire series available on the same label. There will be a new look - the old one is expensive, and is owned by someone else - but the notes will still be provided by Christoph Wolff.

Your series was the first to include the secular cantatas alongside the sacred cantatas, as part of the same series.

Yes, we did those as the fourth and fifth volumes of the series. I knew from the very beginning that, if I did not record them soon, the secular cantatas might not be recorded at all. So I suggested that we begin with the cantatas - both sacred and secular - Bach wrote before coming to Leipzig, but proceed with the complete Leipzig secular cantatas before starting the series of the Leipzig church cantatas. This is indeed how it worked out, and I’m glad we did that. In later volumes you will also find the secular models of some of the church cantatas. When Christoph Wolff and I discussed the volumes devoted to the secular cantatas, we didn’t think of including these models. But as the project proceeded, we both felt it would not cost so much to add these works as well; so now you can find, on the same CD, the secular model alongside its ‘parody’ - the church cantata. This not only makes for an interesting comparison, it also demonstrates that Bach’s sacred and secular cantatas are written in the same musical language. In general, I believe that in the 17th and 18th centuries, music for the church, the court and the theatre belonged to the same mainstream, and Bach’s music was no exception. When you see how many of his church pieces are parodies of music written originally for a secular context, this becomes especially evident.

More generally, you seem to have a strong affinity to the secular side of Bach’s style and oeuvre. In this context, you once criticised some performers for being ‘too Calvinist’ in their attitude to Bach. What exactly did you mean by that?

The word ‘Calvinist’ itself is, perhaps, not well chosen. I was trying to characterise those musicians who approach Bach’s music without a genuine feeling for Baroque music - and specifically, without appreciating the connection between sacred and secular idioms. This connection seems to pose a problem for many people today - but 17th and 18th century ideas of Christian faith, and of styles appropriate for the liturgical music, were very different from today’s ideals. Lutheran orthodoxy in 18th-century Leipzig was not quite the same as Lutheran orthodoxy today; and Bach himself was not a puritan or a fundamentalist. All his music - whether it was written for the church, for the court or for Zimmerman’s Coffee House [the meeting place of Leipzig’s collegium musicum] - is very clearly the work of the same individual.

Obviously, Bach believed very strongly in God. But I don’t believe in Bach the Fifth Evangelist; I think this image makes out of a genius something that he doesn’t need. He was a normal believer by the standards of his time, and this normal belief is strongly evident in his church cantatas. This is the point of view that informs my performances of these works. I don’t perform them as if, in German towns in the 18th century, the only thing people did on Sunday was go to church and read the Bible. For me, Bach was too much a person of the world to be more involved in religion than any other normal person would be; he was no priest. I think that the religious element in his life and music is overrated sometimes.

Bach was too much a person of the world to be more involved in religion than any other normal person would be; he was no priest.

Of course, when I say that, then some people say directly “Oh, he’s better suited for the secular cantatas than for the church cantatas”, but I believe that I take good care to understand what Bach means in his music. I do not try to decipher these works by delving deeply into 20th-century theology, but I believe that I can nonetheless arrive at a correct understanding of the music.

How do puritan tendencies translate into actual performance style? I certainly sense that your performances accentuate elements such as dance rhythms and concerto-like virtuosity - elements which some Bach performers tend to downplay. Is this what you mean by overrating the religious element?

That is part of it. Musicians who approach Bach from a puritanical perspective tend to employ few or no ornaments, and they are too restrained in their application of dynamics, too uniform in their articulation. I think that’s wrong, and results from a misunderstanding. In Sweelinck’s keyboard music, even in the most profound pieces, there are moments when he suddenly goes into triple metre - sometimes only for one or two bars. This is just one example of the same sort of rhythms being present in both dances and church music; and I think we make too strong a division between sacred and secular if we treat these rhythms differently in different contexts. Baroque culture did not make much of these distinctions. If you go into German Baroque churches in different parts of Germany - the Catholic part and the Protestant part - you could see that they employ different styles of decoration and architecture; but in both cases, the church is clearly a Baroque church, employing a style similar to that of ‘secular’ buildings. For example, the preacher’s pulpit could be extremely secular in some of the Northern German towns - you’ll be amazed at the naked breasts you see sometimes, for instance in Stade, - but to people at that time, it would have seemed normal. We, on the other hand, live in a time when the church is losing some of its power, and we tend to make the distinction between believers, or churchgoers, and non-believers or atheists. But not going to church does not necessarily make you a non-believer; you can still believe in your own way, even if you do not feel at home anymore in one of the old religions. And I think one of the good things about Bach’s cantatas is that they can turn atheists into believers, so strong is the affect that Bach’s music gave to the words.
