| Yes, Beppe,
The stomach needs to be loose so that in can move as the lungs fill up and shrink as you get rid of the air.
It's like when you sneeze. You fill up your body and then quickly get rid of all that air you took in. If you tried to hold your stomach tight when you sneezed it would be uncomfortable, unnatural, and painful.
It's a natural process and we need to make playing the trumpet as natural as it can be.
