Hi all, I think I have "stuffed" up my playing. I have been playing really well (I thought) and progressing in the right direction. I have only been playing for 18 months and as a beginner adult was very happy. I sat my first practical exam about a month ago and gained a A+. My teacher has been stretching my range and I finally broke through the A-Top C above the stave. Extatic. I had a great lesson with my teacher playing all kinds of pieces taking me up to my newly found register with very little effort (so I thought). Then disaster......over the next few weeks I have barely been able to play C in the 3rd space!!!! My lips will barely buzz and my air flow has a plug in it! What can I do to fix this. Will a BERP help to unblock my lips? I play Flugelhorn not Trumpet. If A BERP will help does anyone know if it will fit a Flugel?
