It may just be the staff teaching technique coming through in what my argument with this point is, but I came back over this past summer, took like 2 or 3 days to get my horn embouchure back and I am a MUCH better player...I mean like light years from what I started out as. My sound is a HECK of a lot better, and because of lung capacity exercises we did and everything, my air flow in every register is superb, and my musicality...extending through the phrase and all is much improved. I think in this case, like I said, it may just be the teaching technique...most of the mellos that were in my section can probably agree with me. I heard a few of them at the camp this past weekend, and they have also improved a LOT both on horn and mello...I may not be THE BEST player in the world, but for my college I've gone from being about 3rd or 4th best, to being 1st or 2nd...depending on what kind of sound you like (mine being really dark, and the other guys being on the bright side, but sometimes it depends on what you need or like for certain pieces of music) B)
