Beethoven is a very "masculine" composer. His music is unusually muscular, if you know what I mean. Bach's music sounds like it came from a source above the plane of humans imo. I sometimes feel like I am in the presence of that source while listening to his music. I consider that a spiritual experience, and it can be overwhelming.
My genius friend (seriously. He was programming at Hewlett Packard in Mountain View, CA, and they wanted to find out just how smart he was. The IQ test came back genius. He wasn't the type to speak the number. They made him head of programmer training) was (RIP) what guys like Bill Maher don't understand: both really smart, and a "believer". Ya know, Einstein "believed" (knew, actually ;-) in a creator. Knowing as much about the physical universe as he did, I believe it was obvious to him that it didn't create itself.
Similarly, the "rules" governing music (taught in music theory courses) are there by design. Humans didn't create them, they discovered them. And no one more than J.S. Bach. He is considered the Father of Western Music.
