Bit of background:
been playing 16 years, been to uni to study music etc, left 2 years ago play mainly jazz and big band work I play on a warburton 4m with a QM or a 7 backbore on a selmer concept TT trumpet
I practice around an hour and a half a day in half hour slots ish..
and vary my practice to try and include everything!
now I've played in a few commercial bands but recently ive been been playing in a function band with a horn section- me sax and bone
and I always get very tired at the end, so tired that I blow and nothing comes out! my lips stop buzzing
the same happend tuesday night I played lead at big band, I was screaming up top E's and F's really happily with a full big sound, but 5 minutes later I could bairly play a middle C!
Im putting this down to way to much pressure, although I dont feel it at the time!
I play cat andersons 20 minute G around once a week at pppp with very little pressure
any other excersises or tips for playing with less pressure, especially in the upper register?
