Hello, I been trying to work out how to play trumpet properly. The way I played high notes before was rolling the top and bottom lip, thus causing the surface of mouth to be pressed against teeth (stretched to the max) which thus cause the vibration to be really high and thus I could play high notes. However, after 5 min of playing I would need to leave the trumpet for a day which sucked because I used to play guitar for 3-4 hours and now I cant even enjoy music for 10min. Then I received help, found out the mouth is meant to be in its 'normal' position when blowing, and that should produce a note (low C) which it does, however, as I ascend (D,E,F,G,A,B,C) my mouth seems to be getting tighter and thus the middle of the mouth is harder than how it was playing low C.
I did a search on here, and I read "do not tighten the corners", how the hell is one meant to play up high if his mouth/lips are in the position of Low C which is soft and loose. The harder I blow air, the more loud the trumpet is, no pitch change though.
Can someone give an explanation and some pictures of their mouth with mouthpiece on playing the 3rd space C and 4th space E and then taking mouthpiece off and taking photo again playing 4th space E and 3rd C...
I really do not understand at all what is meant to be going on. As far as teacher goes, I have not found someone in Brisbane that really 'understands' technicality to the level I need to be able to understand
Can someone help me please?
