I know this is silly to expect you fixing my embouchure via Internet but since I have no one around to do this please try to help me. This is actually a fundamental question. When setting lips before contact with the MP it's possible to set them in various degrees of rolling them in/rolling out. I notice then when I set lips in normal human position (just like I don't want to play trumpet) and then blow throught the trumpet I get low C and then with some effort I can get up to second line G and can force A out. If I set lips in "M" position, that's slightly rolling them in and blow I naturally get the second line G and can go up to third space C with some work. To get low C I need to drop the airflow and relax the corners of the lips because setting them in "M" position makes them already slightly tightened. To prove this I have to relax them completely to set them in normal human position. Which setting sounds to you more correct? I also remember that I've read on that kind trumpet player and educator Pop's site that beginners tend to part theit lips and that's often a problem. To me leaving lips in the normal human positon sounds like parting them for playing trumpet. Is this correct?
