Talent Gone Unnoticed?

Hi. I have a lot of talent. I can sing. My friends all agree that I am the next Carrie Underwood or Gwen Stefani. I have a super deep voice that's really smooth and clear. All the other girls in my cl have soft little bunny rabbit voices and I'm afraid to sing to my full capacity. And I'm totally unnoticed when I do. This totally mean boy hogs the limelight and will shoot down any attempt I make to go out for a solo. Is there any way I could show our teacher that I am a good singer without drowning out the other girls or looking like a jerk?
