Excellent article with which I completely concur.
There is absolutely no good that can come of a child's 'studying' voice, and even less than none from competing to be a 'star' whether it be in opera, broadway, or any form of pop.
In vocal pedagogy, we refer to the "Annie syndrome"....... the death of the vocal cords of many, talented young girls who pushed too hard too soon.
It is bad, bad, bad in every respect to do this to a child.
(And I really like the author's emphasis on letting a child be a child. NO area: sports, music, or academics, seems to do that any more. For me, it's a tragedy).
