I need help.
I find that I sometimes have air flow issues, but it's usually because I have too much air, not too little. It's been in the back of my mind for a while as something I want to address, but I just found this from Rowuk on one of the sticky threads, and it reminded me.
"2) Efficiency is the proportion of energy in to energy out. In horn design, we get improved efficiency when increasing the resistance at the throat (the mouthpiece in our case) compared to the mouth (the bell). The problem that we have as trumpet players, is that we need to breathe to stay alive and play. That means that we need a certain amount of "inefficiency" to use our air up in the time that our body requires fresh air. A too free blowing horn on the other hand sacrifices efficiency and limits our ability to phrase because our air is gone too quickly."
I usually run into this when I'm playing something that's slow/soft/reflective - say, Bach's Air on the G String. When I'm playing faster or louder, it's not really a problem.
What happens is that I'm done playing a phrase, and still have about 17 gallons of air left that I need to get rid of - like I've been holding my breath too long underwater.
Is there a possibility that I would do better with a more free-blowing horn or mouthpiece, at least for certain pieces?
Or could it be something completely unrelated?
