I'm a french trumpet player. I have been practising a lot on my trumpet lately and I am making improvements. But everytime I try to get to high notes, the sound is "stuck" in my throat.
However, when I take my mouthpiece and vibrate in it, I can go really high. And I can use the right amount of air! But the moment I grab my trumpet and play high, the sound disapears in my throat, as if it was really tight and tense.
I'm desperate to get better, but I always struggle with anxiety and muscular problems, my muscles are always really tense. I imagine that all I should do is to relax my throat for the air to keep going, but I can't.
Do you know how I could relax my throat, and letting the air come along with my lips? Do you know any exercices to be more "relaxed" while holding the trumpet? It is really important to me. I started to get really depressed by the fact that everything is improving except for my range.
