When I was studying music at University, I would always get this nervous feeling when student pianists would play Bach. The intricacy of Bach often defies the phrasing practices of more modern music. Even highly-skilled musicians would have to un-learn long practiced habits to properly navigate the landscape of a "simple" Bach fugue. Myself, I was a trumpet player, so little Bach for me. Nonetheless, I had much unlearning to do before I was ready to properly break rules.
What about Brandenburg #2?
Sorry as a fellow trumpet player I couldn't resist....
