As I am making my comeback, I am choosing the best way to use my top lip. But my top lip seems to be more complex then what I am seeing. I have found that the tissue that is behind the red of the lip is getting involved with my playing. And this tissue that is behind the red of my lip is the tissue that I used to use years ago to give me my rich sound that I had developed. But it also has become a stumbling block because it affects my endurance. I am trying to reduce the pressure that I play with but it is this tissue that is behind the red of my lip that looses circulation and deteriorates my endurance. So I am trying to play with only the front part of the red of my lips. This does help my endurance but keeps me from getting the sweet spot that gives me my best sound. Can anyone relate or understand what I am talking about? I do worry about the makeup of my lips. I see many great trumpet players who seem to have thin enough red on their top lip to fit the whole thing into the mpc.Arturo Sandoval does it.If you look the indentation on the top lip of Arturo right after he plays, you will see that he gets all of the red of his lips into the mpc. My trumpet teacher Leon Merian had the same type of lip. Maynard has it. There was an upcoming trumpet player that was about to surpass Maynard in the early 70's who died in a plane crash. He seemed to have the same shaped top lip as Maynard. His name was Chase if you want to check out a photo in Wikipedia.
