On Being is an NPR show hosted by Krista Tippett. This week, in conjunction with one of the NPR stations here who is having Bachstock, playing his work all November, she interviewed a computer scientist who is a huge Bach fan.
I am not sure this fellow, Bernard Chazelle, is formally educated in music, but he seems to know more than a bit. But I really enjoyed how he frames Bach’s place in music - exploring harmony, focused on the craft of music and the uplifting power of music.
One thing he said was interesting that I want to put out there on the SDMB and hear from formally trained musicians and everyone. He said that Bach’s work is the acme of harmonic complexity. Basically, when Bach explored harmony with, say, the Goldberg Variations, there are 6 equal melodic voices working togehter - harmony emerges from how these equal melodies interact. Because that was incredibly hard to do and also complex, the “rules” evolved to favor a main melodic line with complementary, supporting harmony lines above and below it.
I hadn’t thought of Bach that way - is it a fair way to describe how harmony evolved?
