Yes, since a post a while back on a thread of mine about projection I've realized about the resonance versus loud issue. I think I've been improving on that, I'll continue to work in that direction.
I have mixed feelings about marching and pep bands, but they're paying me for this, so I've gotta do what I've gotta do. Can't hurt to learn to manage movement with efficient playing technique.
I believe I have been keeping my horn straight to my face, but I'll be sure to focus in on that.
Thank you all for your suggestions!
