I have been taking dance for about nine years and I think I am pretty good. The only problem is my dance teacher does not seem to notice me much and I never get solo pieces. I am tierd of sitting in the dark and not doing any thing exicting. How can I get her to notice me?

What type of studio/dance? It almost sounds like you are talking about ballet/modern/jazz rather than ballroom, in which case the answer may be different.

How much individual attention does the teacher put into your development as a dancer? Do you take only group lessons, or private lessons as well? (ballroom question - I get the sense performance dance is mostly group instruction)

I'd be more worried about your opportunities to develop than your opportunities to perform prominently. If it's just performance opportunities that you are not getting, then perhaps the teacher doesn't feel you are ready. But if your development is being neglected, then you need to find a new teacher or at least establish a new relationship with the teacher, as she is never going to think you are ready to perform if she isn't helping you develop.
