Der Herr denket an uns (BWV 196): closing chorus Sep 29, 2025

Show notes

Unabashed joy describes this short and sweet cantata, which Bach wrote at age 23 for a wedding. In its sparkling finale, some mysteries hide. A curiously unexpected tonality sets off the happy declamation of "ihr seid" (you are), with emphasis on "seid"; according to Bach we ARE blessed by God, rather than "us" being special.

Then what do we make of the ending? Even in an early cantata which generally sounds like 1600s Lutheranism, some new special effects are hidden. Bach surprises us with his piano marking along with some Haydn/Mozart-like figurations. It's hard to listen to this level of happiness without cracking a smile.

Song: Vergiss mein nicht (BWV 505) Sep 22, 2025

Show notes

Today we talk "Men in Black", "Coco", "Futurama", and hear a slappin' bass line from an 80's funk song. Oh, and some Bach. Remember to stop and smell the forget-me-nots -- in other words, enjoy those moments.

In memoriam Fred Jacobs.

Goldberg Variations: 16. Ouverture Sep 15, 2025

Show notes

Overtures belong at the beginning, introducing what is to come. So why is one found at Variation 16 of the giant Goldberg Aria and Variations?

Well, it is the beginning, but of the second half of 30 variations. Variation 15 takes us into fear and anguish with a mirrored canon in the (unheard of) key of G minor. After 45 minutes of bright G major since the opening aria, this change into the parallel minor key is stark, but not as stark and bare as the open fifth ending: a lone D string. Then follows a pause (in this performance by Jean Rondeau) of fully 35 seconds.

We start fresh, renewed with the joy of G major after this pause which literally divides the performance in half. The French "Ouverture" is a new beginning, replete with bright and shimmering baroque ornamentation. And yet it fits in the mold of the harmonic structure of the original Aria. While we think that there are beautiful performances of the Goldberg Variations on the modern piano, we lament the limitations of the low end of our big new instrument. Of all the 30 plus the Aria, this variation is the one which must be heard on the instrument for which it was intended -- harpsichord.

Nun danket alle Gott (BWV 192): closing chorus Sep 08, 2025

Show notes

To play baroque music properly -- especially a bouncing jig like this one in 12/8 time -- you must "unlearn what you have learned", and rethink how you articulate music. Articulation is so important -- the music must feel and look light and airy. This performance by the Netherlands Bach Society fits this feeling perfectly -- the musicians look casual yet classy, showing that Baroque music can indeed be lighthearted and fun.

Goldberg Variations: Aria Sep 03, 2025

Show notes

The towering thirty Goldberg Variations combine into a masterwork of keyboard music. As all variation pieces, they were based on a relatively simple source material. But as is his way, Bach organized the variations with a complex and deliberate structure. But also unlike other composers of this form, he poured more into this source material itself.

The famous Aria could stand alone as a sublimely decorated Baroque keyboard piece, but it doesn't stand alone; its bass line and harmonic progression (not its gorgeous melody!) are the actual foundations of all thirty variations. Bach simply could not resist pouring this beauty into even this, the harmonic "template" for the next 90 minutes of music! And this foundation does hold up, all the way until the end, where we are told to play the Aria again, now as our ending.

Baroque ornamentation and performance practice takes this piece past its simple structure. We discuss this ornamentation and one particularly strange and almost inscrutable moment in the middle.

Cello Suite no. 6: Courante Aug 25, 2025

Show notes

Listener HG drew our attention to a similarity between the Courante of this cello suite and the "Cum Sancto Spiritu" from the Mass in B minor. We talk about these dance forms and how they affect the affect, so to speak. Nowadays, it's easy to think of Bach as old-fashioned, and certainly some composers in the late 1700s thought the same; however he shows here that he was ahead of his time.

The "shoulder cello" (violoncello da spalla) makes another appearance here, smaller than the typical cello. The instrument sacrifices the deep warmth of the cello for nimbleness and an extra string which allows for higher notes.

Himmelskönig, sei willkommen: Sonata Aug 18, 2025

Show notes

"An understated overture" is the description Christian arrives at to describe the humility of the micro-regal sonata which opens the Weimar cantata "Himmelskönig, sei willkommen." Is this thing, marked "adagio, grave," actually a triumphant French Overture? The performance suggests so, in some ways, and not in others. Experienced musicians of baroque music will know the subtleties, which we discuss in this episode. Indeed, it is a march of kingly victory, but not in pomp and circumstance; it is the small and gentle arrival of a humble king of Heaven and Earth, arriving to the world as a helpless baby, and arriving to Jerusalem on a donkey on Palm Sunday.

Also, featuring Rage Against the Machine and a very unsettling "Shepard Tone"!

Himmelskönig, sei willkommen: tenor aria Aug 11, 2025

Show notes

This cantata has an unusual run of three arias in a row -- and the last one of the three is the most remarkable. In deleting a note, creating a rest where there should be music, Bach breaks all the rules -- and creates a stunning effect.

Sonata for Violin and Harpsichord in G major (BWV 1019c) Aug 04, 2025

Show notes

Bach used the materials for this sonata several times throughout his life. Each collection of parts is different, and there are three versions. This is version 1019c, as labeled by the BWV categorical system for Bach's works. There are five parts of this last of his six sonatas for violin and harpsichord. We discover the joys of rhythmic ambiguity, rhythmic complexity, and even a middle movement without the violin! (And yet sometimes this is called "Violin Sonata in G major," shirking the credit of the keyboardist.)

Christian focuses in on the end of the 4th movement, where a short ending extends and wanders into a surprising and somewhat tonally unclear ending. But it is made clear in the next moment, when the joyful key of G major returns in the jaunty final allegro.
