I started playing trumpet last August. I went to an instructor every week for 4 months and have been learning on my own since December. Unfortunately, I just discovered that my lip placement does not seem to be right, which is causing me trouble hitting higher and lower notes. From what I've read, air flow from the lips should be going straight out in front of me. I didn't know this when I first started, and developed a habit of tucking my bottom lip in and blowing down across my bottom lip. When I buzz my lips, I can feel the air stream on my chin.
Anyway, I'd like to correct this ASAP. I've done some breathing exercises by blowing air straight out, and practicing with the mouthpiece. I'm getting a new instructor this week to help, but does anyone have some advice?
This is so frustrating because I spent so much time learning the wrong way and felt I was playing fairly well, but I hit a wall because I had to use pressure from the mouthpiece to play high notes, which killed my chops.
