I really love singing. I do it quite often but I get really nervous about doing in front of an audience; even just thinking about it makes me nervous. I guess this is strictly related to everyone's personality and I've searched around for tons of helpful tips or guides to help you overcome this. But these helps were mostly on the psychological side: get on stage and you'll get rid of stagefright, forget negative thoughts, don't give too much importance to fear, etc.
My question here is mostly about a different, yet still related, problem. If the problem was only sweaty hands, shaking (usual nervous symptoms), I wouldn't mind at all. The problem is that this nervousness directly affects my singing.
My throat, and here is the problem, basically gets blocked. I can even feel it coming, a feeling of my throat getting clogged. Perhaps this is usually referred to as "throat getting dry", but I feel as it closed for a second, and after that I need to swallow before being able to continue.
Setting aside the psychological part (which I suppose is off topic here?), is there something I can try to overcome and avoid this obstacle, no matter how much I feel nervous?
