Hello all, Just a quick question; I am practicing my trumpet and this morning, when I tried to play up to a high G (sitting on the staff) the sound would be just air and no sound, and maybe a squeak of the G, which is normal. Just now, I am playing a bit before bed and my high G is not just air, but sounds broken. Is this good? I mean, before I could get nothing at all, but now I get a broken G. I'm pretty sure it is my loss of air, so I am working on that right now. Any tips on playing high range?
