Vocally, Academically, Intellectually and Artistically Speaking… Is there a balance needed between all of those listed components?
My answer would be, “I honestly do not know”.
Peculiarly enough, sometimes, they are “saved by the bell”, so to speak…
Believe it or not, it actually happens in some cases, even with the almost complete absence of natural talent.
The rest, so to speak, of a street level, usually have talent galore, but to teach them anything, which requires some academic skills (along with their natural talent), is virtually a nightmare in a lot of cases.
