Question: When you play, where is the air flow directed into the mouthpiece? I've recently noticed that I tend to tilt my trombone down slightly, so that the air stream presumably hits the top of the mouthpiece cup. I found that by angling the instrument up a bit so it's more perpendicular to the head, I got a bigger sound. I'm thinking this is because the airflow is going straight down the centre of the mouthpiece. It feels a bit strange playing this way because there is less pressure on my bottom lip. Does this make sense? Any comments?
