Last night i was playing all my band music 3 times (3 songs all three 2 pages) to get ready for our band competition. after that i wanted to have fun so i got out my star wars music book and my 14a4a mouth peice cuz my lips were hirting. after 50 minutes of practice i couldnt play anything at all because my lips hurt from playing, what whould i do to stop that?

build up your endurance by play`n really low petal tones a lot bout 10-15 mins everytime you practice!!! Believe me I had this problem for about 4 1/2 yr but just a few months ago I started this and I can play like a marithon runner can run good luck and keep up those low tones and a good a least 15 mins of warm up before you play
