I hope that you can find some stuff in here that will put you on the right path. My intent was not to tear down anyone for suggesting a mouthpiece switch, nor to discredit exercises that Wayne Bergeron may (or may not) do to keep his playing at the extreme level he has attained. My intent was to pass along my opinion based on personal experience - and keep in mind what is elixir for me might be poison for someone else. I can't really advise you what to do with the horn - what I can do is relate things that have worked or mistakes that I have made by being primarily self taught, which in retrospect, I don't recommend for anyone who really wants to advance as a player. While a certain amount of progress can be made in self analysis, it may take years to come to a conclusion that a good teacher could have turned you onto in a couple of weeks. Anyway, with all of that out of the way, I would like to personally welcome you to the forum and community we have here. You will find a wealth of information from some truly top notch players, and the atmosphere is light and conducive to building some really neat relationships.
