So we had a spring football game on the 23 of May. It was great and I had fun playing around with my great high range.

Well something happened. And I don't know what. My range that night and for a while prior was up to a strong double C. Ever since that night, I have been STRUGGLING to get a regular above-the-staff C, which is an octave lower than the double c which I had perfected.

Does anyone know what happened? Cause marching season is coming up very soon and I play first trumpet. :-/

Help????
