You start out singing naturally, you don't think about how you sing, you just do it, and you sound like yourself.
Then you start messing with it, you get louder, or richer, things feel really different, you think about singing again. You wonder why singing is so much harder than it used to be, and how it is that you could be better if it's so much more work.
Then somehow that goes away, and you're just singing again, and you just sound like yourself again. But you actually sound different than you sounded before, you're just now used to the new way you sound.
rinse and repeat.
Ideally technique should be making everything easier. With the correct technique singing the high c is really nothing at all, especially if you have the d and e above it. But you know it's high, and frequently you make it hard for yourself to prove that it is high.
I'm in a period of vocal ease again. It's very strange because once you stop thinking about these new things that you've developed, you sometimes start to worry if you're accomplishing them when you're not thinking about them. That's where I am. I'm singing and it just sounds like me, and I'm not sure if I've carried all my developments with me in a period of taxing vocal work. I think I've done moderately well at least, but it is very hard to tell from this end of things.
