Thank you for following this blog, and thank you for reading this long post all the way to the end!

For Trinity 11 (August 8 in 1723), we’re listening to Cantata 179 Siehe zu, daß deine Gottesfurcht nicht Heuchelei sei, with a superb opening chorus and one of the most beautiful soprano arias Bach ever wrote.

I prefer Bach Collegium Japan’s recording of this cantata. It’s a special recording, with Miah Persson singing the soprano aria. She’s having quite a career now, so I think we’re lucky to have her beautiful voice and sensitive interpretation on this recording from 1999. You can find it on Youtube or Spotify. Please consider purchasing this recording on jpc.de, Amazon, or iTunes. Soloists on this recording are Miah Persson, soprano; Makoto Sakurada, tenor; and Peter Kooij, bass.

Please find the score here (it’s fun to read along with the recording, especially in the opening chorus, to see what Bach does with the fugue) and the German text with English translation here.

It is now more than two months since Bach started his new job in Leipzig, and he is about three weeks into writing a brand new composition every week, and I’m sorry if I sound too casual here, but he’s on a roll. He must now have a vision of what it is he really wants to do for these churches (see the tiny preludes to his Passions he incorporates in cantatas 105 and 46), and he must have the classes at the St. Thomas School organized, and his singers sufficiently trained, so that he can now have them sing a new and challenging opening chorus every week.  Just listening to the opening choruses alone, starting with the one of cantata 136 for Trinity 8, I marvel at what he comes up with every time. Every single one of them is stunning, but at the same time completely different from the one of the previous Sunday. This time Bach chooses to write a perfect “old style” (Palestrina-style) motet fugue as opening chorus.

As always, to fully understand the cantata and not miss any of Bach’s hidden messages, it is important to look at the Gospel reading for the day. In this case it is the parable of the Pharisee and the Publican (or Pharisee and the Tax Collector), a story Jesus tells as an illustration on how to pray: the Pharisee is full of himself, telling God how good he is, while the Publican in his own prayer merely asks for mercy, and tells God how bad he is.  This concept of “how to be a good Christian before God” was very important to Bach and apparently his librettist got the message loud and clear. He or she uses the opportunity to first write a strong protest against fake religion and hypocrisy in “Christianity today” in movements 1 to 3 (probably having certain people in Leipzig in mind), after which he/she states that all Christians should take the humbleness of the publican as example in movements 4 to 6. For another example of how Bach interprets this Bible story, read my post about Cantata 113, written for this same 11th Sunday after Trinity, in 1724.

The most special feature of the fugue in the opening chorus is that since the text talks about beautiful outer appearance versus a bad character, Bach uses a mirror-fugue, which he used as well in fugues 5-7 from the Art of the Fugue (the theme of six bars is first introduced by the basses, and then is answered by the tenors in an “inversion:” every step up from the basses becomes a step down in the tenor part.)

To understand how Bach built this intricate fugue I am sharing the excellent music example and diagram by Dutch Bach writer Eduard van Hengel, with his permission:

Even though the text here is in Dutch, the diagram speaks for itself, with this quick explanation of the numbers and symbols:

1 = The theme (or first half-sentence of the text: Siehe zu, dass deine Gottesfurcht nicht Heuchelei sei). Note the ascending line on the word “Gottesfurcht” (fear of God/love of God) and the descending line on the word “Heuchelei” (hypocrisy).

2 = The counter-subject (or second half-sentence of this text: und diene Gott nicht mit falschem Herzen). Note here that there is a chromatic line every time the word “falschem” appears in the text: for the chromatic line the composers needs accidentals that are not part of the key the piece is written in, which in the “old polyphony” would be seen as “falsch” (not right, off-key).

Upward arrow = fugue theme regular

Downward arrow = fugue theme inversed (mirror fugue)

2* = a more compact (only 4 bars instead of 6 bars long) theme which is derived from the first counterpoint/counter-subject on the words und diene Gott nicht mit falschem Herzen, still with the chromatic line on falschem Herzen.

The numbers at the top are measure (“maat”) numbers.

Bach himself must have greatly valued this cantata. About 15 years later, he used no less than three movements from this cantata for use in his short masses, or Lutheran masses.**

The opening chorus was later “recycled” as the first movement (Kyrie) in the Mass in G Major, BWV 236. Keep listening, or scroll to 18:00 and you’ll discover that the tenor aria Quoniam (sung here by Thomas Hobbs) was, with some changes and a much slower tempo, recycled from the tenor aria in this cantata 179. In cantata 179 the tenor aria gets a colorful accompaniment of two oboes and first violins in unison. The second violins and violas fill in the meaningless middle part (representing the “nothingness, emptiness”). When recycling this later for the Quoniam in the Mass in G Major, Bach uses only one solo oboe for the accompaniment, and completely leaves out all strings (confirming that with a different text, the meaningless middle part is not relevant anymore).

This cantata’s wonderful soprano aria (with two oboi da caccia and basso continuo) was later reworked into the Qui Tollis for the Mass in A Major, BWV 234 (with two flutes and only high strings as continuo). This was actually how I first knew and loved this soprano aria, I didn’t know cantata 179 until I started listening to it for this blog. Please click on this link and listen to the amazing Agnès Mellon sing the Qui Tollis from the Mass in A Major.

** These are called “short” or “Lutheran” masses because they consisted of only the Kyrie and Gloria part of the traditional Catholic mass. Bach wrote four of them (BWV 233-236), and they are all made up of existing movements from cantatas, but reworked and compiled in a very smart way and they are all absolutely beautiful. You can purchase an album with Herreweghe’s recording of all of them on jpc.de, iTunes, or Amazon.
