Well, I see that not much has changed in more than twenty years. I was a teacher of voice, piano, and music theory at this place for the better part of the Eighties, and the best way I can describe their approach to teaching is ""assembly-line instruction:"" get 'em in, get 'em done, get 'em out, and make sure you get their money.
The claim that students can have all the time they want is a lie wrapped in the truth. They can spend all day working at their theory papers if they so choose, but on a busy day some of my voice and piano lessons got cut off after barely fifteen minutes with the student and nothing I said or did changed things one bit. The only reason I stayed as long as I did was that the job fit my schedule, and while the money wasn't great, it kept body and soul together. But in all the years I taught there I can count on fewer than ten fingers the number of students that actually learned to play their chosen instrument or made any significant progress cultivating their voices.
Don't send your kid there unless all you're looking for is a babysitter.
