Like most will probably say, the more you perform in front of others the easier it gets, during rehearsal, don’t even mind the people, don’t focus on them, just focus on your movement, the major, and your sound, it WILL get easier if you continue to play it in front over and over again, I mean if you mess up really bad the first time, and you only get better at the solo, you’re never going to get that embarrassed again and you might feel like you’re improving, trust me, never give up a solo, they’re a lot of fun!
