This might seem like a stupid question, but I really want to know because sometimes you can practice the music wrong and then be used to playing it like that and then when camp comes, you're all confused because that's not how you know how to play it. Also, if I practice too much, I can easily get burnt out on my music, as I play trumpet and it makes my mouth sore when I practice for 4 hours at a time, lol. So, I'm just curious. Thanks.
