Hello Everyone !
I will say at the beginning that my English is not good.
I'm not from here, but I need some help :)
I play the trumpet for 10 years. I finished school and now I'm in music college. About a year came to me unusual problem. Generally always I played loose and everything was okay. Now I have a strange hesitation condition. Some days I play great, some very bad. When it is bad,
my lips are weird, rigid, and I have the impression that they do not want to vibrate. Always I did not need warming up, my lips have always been sensitive to air flow. Situation is repeated every few days. Some days great (range, sound good), some very very bad :(
I exercise regularly ever since. I tried many exercises and nothing helped.
Several week break also no effect. I spoke with many people and no one could help me. Some people said: "Too much exercise, too little exercise", but this is not true. My embouchure is good, because if it was bad all the time I had this problem.
I think I have explained what is the problem,
I count on help from you,
