If you have the propensity to look at an equation and see the sublime and the beautiful, then you will see it in Bach.
Music is per definition still completely different from mathematics.
I personally, but many others too, love bach because he has to say something, a message to deliver in each one of his compositions, just like every other (good) composer.
I think people focus too much on the mathematical aspects of his music. They are only means to an end. What the listener captures in the end are never the mathematical implications and the complexity (and simplicity) of how the voices interact with each other, and i have never seen one who can understand them by hearing, it always requires analysis of the score.
The result, i.e. what finally remains when listening to bach, is - imo - never architectural, but organic, and for me is never *only* intellectual, but also emotional, since one can't exist without the other.
