The size of the audience really isn't a factor..
The only folks that we can see are the people in front of us... not much different then the 100 people we play for at a senior event..
That's a good way of looking at it!
my first concert solo performance was at the age of 12.... on accordion.. I didn't know I was suppose to be nervous
I was so nervous at the high school talent show, when I heard my name called and went through the curtain opening to arrive on the stage I almost fainted. My presentation song was Frosini's "The Jolly Caballero." I played the introduction, was so frightened I forgot the whole middle part, and went right to the ending. Total performance time about 12 seconds!
