Let's call this one "How to Break a Chorale."
A Bach chorale is a pure, simple expression of a hymn tune. Sometimes it contains complex harmony, but the harmony is always in support of a song that the people knew, and the texture is simple and chordal. This is why today's moment feels like a bolt of lightning from the blue! It's a chorale for a few seconds...before it stretches apart at the seams. Four separate, strange tones tear the fabric of the chorale at the word "death." The chorale reemerges happily and hopefully.
