My young classical singers all want to sing opera but I won't let them until they've had more technuqie and more growth. However I do allow my eleven year old girls to sing several arias bordering on classical. Check out Emily at age 10. If you like any of what she does (http://www.mp3.com/Emmy) I can get the music to you. You also might check out Katelyn's singing of "Come To The Faire" at age 12, but more of a challenge for younger voices. (Katelyn's link at below)
