Well, I don't really play the trumpet, I play the coronet. It is the same as the tumpet except it is shorter. The one I play is a silver Eterna by Getzen. I have been playing it for maybe 2-3 years total. Playing it came natural to me, all music does. Not to sound conceited. Anyway's back to what I need help with. My school band is going to attended Massed Bands again this year, and the some my teacher picked for us to play has a ton of high notes. The first few weeks I could hit all the high notes just fine! High A and B's and a few Cs. I am talking about the ones above the cleft =p. But fior some reason, like the past week and a half, I have not been able to hit them, my horn just blows air and makes a scraggly tone like I was just starting to play. I don't know if this is important, but this all started happening the second after I cleaned my trumpet. I don't know what to do! We are performing in about a month! I have been practicing for like an hour every day at school, and an additional hour at home, but I still have trouble hitting the high notes that I used to be able toh it so easily. WHAT'S WRONG WITH ME/MY HORN!
