Hello, I was just wondering if most cornet or trumpet players curl their lip to the inside when placing the mouthpiece on? The mouthpiece tends to slide from the place i placed it to another, and I curl my lips right before playing. This issue is preventing me from playing something long. So... Is the lip figure different from person to person? Or is there only one embouchure formation that is worthy? I used to just place the mouthpiece on my lips without curling them, and it worked fine, but then I looked at the pro players and it looks like they do something, don't know what but something with their lips right before placing the mouthpiece.
