I was wondering, as far as injuring yourself from playing incorrectly for whatever reason, how do you know the difference between an injury and just playing too hard? And, if you're not injuring yourself, are you still building and getting stronger? For example, an athlete can go out and train hard and be sore the next day or two, much like I feel the night after a long 4 hour gig. That athlete hasn't injured himself, and in fact, a lot of times people say, if you're not getting sore from your workout, you're not working hard enough. I'm obviously not injuring myself, because as I take a day off and then come back, I feel stronger each week. But it got me thinking, for those of us that can't hit a double c while resting the horn on our pinky fingers w. absolutely no pressure at all, is it hurting us in the long run to use pressure to get the job done, or will our lips eventually get so strong from playing all the time that we can gradually become more and more efficient and not have to rely on muscling the horn so much??
