When I was in elementary school our choir was audition only. There were twenty spots ten boys and ten girls. It was when I originally realized that I might actually be an ok singer. I went on to participate in many other choirs that had required auditions. My best friend did not get picked and that was awkward. Honestly, I think children not being able to do things is fine. Not everyone meets requirements for a school's gifted program in elementary school and that is ok. Some people are just musically talented and some are not.
