Now boys (and girl), am I and my cadet friends gonna have to step in to bring the peace? You're supposed to be setting an EXAMPLE for young Andrew here. This means Van, no beating the pupil. Think how we'd have reacted if we'd have been beaten. This should satisfy Lara, and keep me and Bear in TX (which is good because I have a calculus 3 final tomorrow that's gonna tear me a new one and then some). Comprende? Now, for the actual matter at hand. First, I'm assuming we're referring to an air pocket here. I think you might be well suited to remember to relax when you play. Don't try to force anything. Just hold the horn to your lips enough to make a solid buzz. You might also be trying to smile when playing the horn. Just keep the corners tight, and allow the air to flow. It's kinda hard to really say what to do because 1) I can't see you play, and 2) I don't really know enough. Further advice: Anytime Manny offers advice, listen to it. It's amazing how much it can help sometimes.
