Arrggghhhh!! help me before i just send myself crazy! How do you play highnotes on a cornet!? I've been playing for nearly.. 10 years now and do practice still!! But, unless im really really warmed up i cant hit hhigh notes and then its only for about 10mins! IT's driving me mad! I know i don't have the best embochure (or however you spell it) talk about a bad habbit, I press my top lip on the mouthpiece -but i've tried to swap it and it either just slips back to how it was or i can't play at all. It's driving me mad! i know to practice long low notes but what else can i do,... apart from go play horn PLEASE SOMEONE GIVE ME SOME GOOD ADVICE!!
