Here is what I observed from one of my companion in the band.
He picked a trumpet and the mouthpiece common pressure made him feel that his lips are softer and not so thick, but the embouchure is firm.

Do you know of some methods or exercises that can make our lips harder or a little thicker so the trumpet moutpiece pressure will be a better feel on the lips??

thank you

what?

maybe a cosmetic surgeon can help ha ha...

I guess you're asking for natural ways of lips enlarging... or to make them harder.

Why would you want to increase mouthpiece pressure?

Ok, I'm interested on the topic how a trumpet player can make his thinner lips a little thicker harder so that he can feel comportable and play better. I'm assuming mouthpiece pressure is lesser, and just thinking of only one factor to improve his feel of the mouthpiece, to make his lips a little thicker harder.

Any suggestions?? Thanks to all

Your question is not making any sense.

Thicker lips or 'harder' lips do not make a difference in how comfortable buzzing feels, or how comfortable a mouthpiece feels on them, or how well someone plays.

And in fact many of your top notch players have thinner lips. Mouthpiece pressure is not less on thicker lips. You might think that more lip will allow the pressure to be dispersed over a larger area, but that is not the case here. With thicker lips you would probably need more pressure. Thicker lips usually have more skin or more adipose tissue. This will give you less control of your lips.

My suggestion is to go back to suar one and discuss the problem before we discuss a possible solution.

So square one - you don't feel comfortable with your mouthpice. Why?
Is it too cold?
Is it to hard? - Does it hurt your teeth? Are your tetth even across the front?
Do you use more pressur eon the top lips or more pressure on the bottom lips?
What angle is your instrument at? straight out at 90 degrees, pointed slightly down at 69 degrees?
Does the outhpiece feel okay for a few minutes and then it bothers you?
Are you playing high notes, medium notes,or low notes? Does the mouthpiece feel good in any of these ranges or really worse in any one of these ranges?
