We're 2 different cliques, and I think I love her and that she doesn't even feel anything toward me ): Help?

We're both 15, and I'm in the 'jock' cliques. She's a musician, she hangs out with the band, orchestra, and chorus kids, and she's nice to everyone but she thinks I'm just a charmer and she doesn't act so kindly toward me, she just ignores me basically...Well, I have made some mistakes by dating the 'easy' cheerleaders, and the saying is 'If she's easy she won't be amazing, and if she's amazing she won't be easy' God, that is true. She has to teach me how to read music now for my art credit, I have to join Chorus for 1 year. I can't read music so the chorus director set her up with me. She was pissed, to say the least, but didn't show it. She just gets down to business, and I try to get some personal info out of her like what she likes, for example. She's too difficult, and hard to crack. I know it won't be easy to get her to atleast talk to me, or better yet fall in LOVE with me, but I don't know what to do or say when I'm with her. I want her to know I'm not a man ...And that I'm not charming her just to get into her pants. please help me...thanks
