It is what we call “the performer’s nightmare” or whatever other people want to call it. The point is that this is a bad thing for all guitar players. When the nerves kick in, everything falls and crumbles down. And if you do not know how to control it, you might be in for some of the suckiest day of your performing life. Luckily, this ain’t permanent diseases. You could actually conquer this if you want to. So if you want to know more about this, you have come to the right place. This would give you the answer to your problem.
First and foremost, the most effective of method of cancelling out stage fright is to don’t think about it. The more you think about it, the more it gets amplified. So the next time you step into the stage, think of other things. Relax, it’s just a show.
Another solution to this problem is to do it for the sake of music and your own satisfaction, not because of other people. If you try to please the whole crowd, it would be much more difficult to cancel out stage fright. Do it for yourself and you’ll see the difference?
