Hi everyone. Am just looking for a bit of advice. I play in a championship section band, but have been told I must change my embouchure (sp?). I rest the top of my mouthpiece in the middle of my lip, instead of on the muscle above the lip. This has proved no problem so far with my playing, which is of a decent standard (I think, anyway), but I have recently been told if I don't change my embouchure this could lead to problems later on in my playing career. I have been told that it can lead to blood clots/ nerve deadening (sp?) in the lip, meaning I won't be able to play. Does anyone know if this is true, or have a similar experience? I have tried playing in the 'correct' position but I can barely produce a note, and can hit nothing above a middle C. Please reply, I'm desperate for advice. Cheers.
