audition song suggestion?

I'm auditioning for the all female hiển thị choir at lâu đài High School, the Knightengales. I'm running out of time to pick a song and I figured bạn guys might help me.

The song needs to hiển thị off range (mine is very wide), and be rather short in time. hoặc it could be part of a song. I only have about 1 một phút - 1:30 to sing it. It also needs to be something that i can find đàn piano âm nhạc for hoặc but an accompaniment for.

Thanks!
