Hi there. I'm on vacation out of state until friday, and I didn't have room to bring my trumpet, but I did grab my mouthpiece, hoping that I could buzz often and still retain my ability when I got back. I've heard a lot of bad news about playing with a practice mute and nothing else, and was wondering if anyone had advice or words of warning about doing only buzzing for a week or so. Would I be better off not playing at all? I am doing the 'pencil excercise' each day as well. Thanks for anything.
