So, I have band auditions tuesday at my high school and the trumpet section is pretty competetive at my school(in skill, we are all friends ) Anyway, I was practicing for a good part of the day today due to my stubborness of wanting everything be perfect and I think I might have blown out my embouchure. A few minutes earlier I was playing through my piece and I could not sustain tones for a long period of time or hit any notes above C on the second ledger line and the notes below it sound out of tune. How bad do you think my injury is? It's not to the extent of pain, just to where my performance suffers to an extent. Maybe the muscles are just tired? Think It will be good by tuesday? I want to do well so I can stay in my higher band. I have a concert tomorrow night as well if that adds to the problem. Thanks in advance guys!
