I'm a classical musician and yes, I have occasionally suffered from stage-fright, sometimes to the extent of throwing up before I go on.

However, I find that there is often a direct relationship between the degree of fear and my confidence that I am able to do the job - if I'm not sure whether I can manage it, I'm scared - if I have practised something to the point where I know it cannot go wrong, then the fear is much diminished, down to the point where it is an asset to playing and puts me "on edge" as it were.

Although I know that it is not always the only answer and that there are sometimes other issues involved, practice can do a lot to help.

Cheers,
