Sound of Music Auditions help?

I'm auditioning for The Sound of Music in three weeks too! And I'm trying out for Leisl. I think you would be fine for Leisl. I just turned fifteen in February. And Leisl is a Mezzo-Soprano. Sixteen Going on Seventeen goes up to a high D so I would sing a song that has that note or higher in it. I am a soprano and I am singing Home from Beauty and the Beast which goes up to a high F sharp. Other than that I think you would be great. Just give the audition your all and you should be fine!
