Martin Luther, J.S. Bach, and Reformation Sunday -- this most Lutheran of all cantatas is our subject for today. "Ein feste Burg" was the battle-cry of the Reformation: "A mighty fortress is our God!" Bach's cantata weaves in all 4 stanzas of Luther's strong hymn.

We marvel at movement 1 with its "dizzyingly complex counterpoint" (as Richard Atkinson puts it in his video). This is one of the maybe 2 or 3 most complex opening chorale fantasias in all of Bach's cantata ouevre, and that's a high bar to clear! But then we zoom in on a more tender moment, the end of the alto/tenor duet in movement 7: "[the heart] will finally be crowned, when it slays death". Here, the bass line drags down in twisting chromatic motion, the tempo slows, and Bach resists the urge to return to an "A" section of text, instead closing the movement with a short instrumental coda.

"In Your Eyes" by Peter Gabriel, a song that was referenced in this episode. The last minute or so of the song features the dense instrumentation that Alex mentioned: 2 bassists, 2 drummers, etc. Also, here is a great episode of the podcast Strong Songs which breaks down "In Your Eyes".

The organ, a sacred sound, gets an unusual role in this cantata for solo voice. We hear the organ leaping all over with a virtuoso part against violins and oboes and the alto soloist. There is no better way to convey the rich concept of the "confused joy" of the believer who witnesses miracles.

In this cantata, which took place during the Sunday where the story is read of Jesus healing the deaf and mute, Bach sets his poet's words:

Spirit and soul become confused, when they gaze on Thee, my God. For the miracles they know, And which the people tell with joy, have made them deaf and mute.

Organist Katrina Liao joins us to talk about one of her favorites, this chorale prelude that is crackling with spiritual fire. The off-beat bass at the beginning is a neat touch -- could Bach have meant to signify the Holy Spirit by focusing on the 3rd division of the beat? -- but, Katrina's favorite moment comes in the second verse, when the bass gets to carry the melody with a strong, reedy pedal sound. Christian also points out a hidden "B-A-C-H" motif.
