ET, I'm not sure what you expect here. You've come to us with a question, have told us you are having problems, and have told us that you've only played for 3 years. No one, and I mean NO ONE, can "fix" your embouchure problem with some sort of trick or sage words of advice that are all of a sudden going to take your chops and fix them inside of the 3 weeks you seem to be expecting. I've got news for you - if you are having issues with your Eb scale today due to some embouchure issues, you're probably going to still have some embouchure issues after school starts, regardless of what anyone here says - Like Peter McNeill said, no one can wave a magic wand and make your chops do something. Here's the simple truth - you need to work at it. Period. For most things related to learning to play a musical instrument, you need to put in a lot of focused time in the practice room, and I'm not talking an hour or two a day for a couple of weeks, I'm talking an hour or two a day for several years to develop, and then for the rest of your life if you expect to maintain it. There are a lot of people in this thread, myself included, who have made their living, or are making money with their horns, and there is a reason for that - we've put in the time to develop our chops, technique and musicianship to a point where we can. I know in my case, while certain things did come naturally for me to a certain degree, I also put in thousands of hours in the practice room and in rehearsals, and that was before I took my screening audition to get into the Army band program back in the autumn of 1988. Since then I've put in quite a bit more time. Right now I'm typing this to you from my practice room where I've just gotten done playing long tones as part of my warmup - long tones that help to maintain strength and focus in my embouchure so I can continue to get paid for gigging. I practice what I preach. I apologize if the wonderful advice you've received all throughout this thread wasn't quite what you wanted to hear, but you might want to take a few minutes to re-read this thread, reconsider what has been said, and apply some of it - especially that bit about getting a private teacher to guide you through some of the stuff you'll need to do in order to better develop your chops.
