I'm a violinist (or used to be ...) as a violinist we were always seen as the forefront of the orchestra- its the lead violinist who steps onto the stage just before the conductor, its the lead violinist who shakes the hand of the conductor, its the lead violinist who is named at the top of the orchstra list, so thats what I am used to being part of. However, I was never a lead violinist, I was within an orchestra, a supporting artist.
For that reason I think I'd be in the background. I think I'd be some sort of supporter who runs things behind the scenes. Maybe writes the lyrics (if I had that type of skill!) but probably be one of those dress-in-black, never seen or heard grafters.
Think I'd be way too shy to appear as a musician in my own right! I'd love to be the center of attention though, just don't think me being the center of attention could ever make a lasting band!
