As a trumpet player who swithched to Baritone in 8th grade it made NO DIFFERENCE to my director because we always had TC parts and I was the best baritone player. When I made State, the other BC players used to come to me with that junk. What difference does it make other than that of convinience and not wanting to transpose a part. You can either play or not play. What if I was blind. I COULDN'T READ ANY CLEF. And I would STILL be able to play.
