We weren't natural singers like you, Ron. We need this extra research because we're still figuring out exactly how to do it! Also though, probably like you, we can't stop researching because we teach. We need to stay up to date not for ourselves, but for our students similar to how doctors need to test every few years to continue their practice. Because doctors are like us.
We see the client. We assess what is good and not good. We prescribe what we believe to benefit the client. It's a continual PRACTICE based on current beliefs and science!
I've taught so many free lessons to get to where I'm at. At master classes in college, I would assess as fast as I could how to "fix" everything that the singer could "fix" and see how the teachers responded to see if I was full of it or if I was getting better at assessing others. I still continue to practice. When people bore me, I just listen to their voice and assess what they could do to better their speaking. I remember helping numerous friends in college on trouble spots they were having. I figure if I can help an advance student, I should be able to help beginners. NOT the case! LOL
Even when I sub for elementary school, each grade is different. K-1 are getting their feet wet. Some get how school works right away, some don't. 2nd grade is the first year they really got it together. 3rd grade, they know the rules, and they stick to them (possibly my favorite grade). 4th and 5th graders think they're adults. Uhh...no, boys and girls...
There are a lot of people "stuck" in this 4th and 5th grade mentality where they think they can sing/teach other people how to sing. In reality, they're just really advanced 4th and 5th graders who think they're awesome! Luckily, when you're 9 and 10, you keep growing, which shows that were weren't as grown as you thought. How can we do that with the similar singers and singing teachers?
