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?

Take a break every 30 minutes.
