I started playing the trumpet when I was 12, done it for a few years then gave up, however, I've started lessons after an 8 year gap of not touching it, I've had lessons for about two months, but I've been having some problems:
I find that the tone of the notes isnt very good, or very 'musical', is this something that will just improve its time?
To hit higher notes I seem to be pressing the trumpet against my face which results in the notes sounding 'squeezed' out and after about 20 minutes of playing I have a very noticeable mark on my lips where the mouthpiece is
My tutor also talks about how my tongue placement needs to change when playing different notes etc, yet I have a bad habit of just keeping mine at the roof of my mouth.
Finally, my air capacity seems to be quite poor as well, I've heard a spirometer can help increase it, but I'm not entirely sure
I'd appreciate any advice I can get on this, I've been getting rather frustrated that I'm not improving as quickly as I'd like to
