One of the main reasons I don't play clarinet that much anymore is that my upper lip always got irritated after playing. The two sides of my upper lip got slightly torn and made them a bit rough to the touch (lick?). I'm not sure I'm explaining it very well, but can someone tell me if this is a natural part of playing clarinet or whether it is attributable to a bad mouthpiece. My clarinet was very cheap and a stock used mouthpiece came with it so it wouldn't surprise me. If it isn't normal, I may buy a new mouthpiece and start playing again, since it is very fun.
