I'm sort-of a comeback player, in terms of "classical" music, having been a jazz player almost exclusively for the last 10 years. I'm now in an advanced degree program studying trumpet, and so I've been working pretty hard on the playing this year--mostly on fundamentals and efficiency/relaxation. One of my goals is to be able to perform some challenging literature on the picc. It's been about 8 months since I began playing picc, and I can only handle things like the Handel Suite in D and the Clarke Suite. What does it take to go from being a "meat-and-potatoes" trumpet player in terms of range abilities to being able to play the Brandenburg? It sounds silly to ask but I want to know if it's even possible to get there, or should I just accept the fact that I don't have those kind of chops?
