As someone who listens to a lot of "Classical" music (more late Classical, early Romantic if we're being specific) I've never really understood the modern universal appeal of Bach.

I find so much of his music quite impenetrable and kind of overwhelming. Things like the Cello Suites with their single line of music very demure. Whenever I try to listen to the Well Tempered Klavier as a set I'm quickly saturated by the third or fourth pair...

It's usually not until I sit down at the piano and play Bach and read the score that I'm then suddenly profoundly moved by the almost divine quality of his music and the "just so" genius writing of his music. But being truly honest I struggle to hear it at face value often - am I just slow / a poor listener?
