I had my braces taken off in September after Jazz Band(high school) had already started. I am first trumpet so I had to take the notes down a lot until I got them off. When I got them off, I tried to jump in right away, trying to play high and get back to normal, having Jazz Band every-other day. Another user previously said that I can't take it too fast because it may allow me to develop a bad embouchure which may cause later problems. I have been playing for two months and trying all sorts of excerises, relieving pressure, and I haven't been able to feel the same or get my range up. What do I have to do?
