Hello, again. As there are many techniques, I'm not going to go over them all. There are really two main ones, and then the one I use. There are the Classical, the Speech Level Singing, and then what I use. I call it Constriction-Free. It's a rather efficient mix of the two, but it requires a lot more out of the singer. There are also many styles. Also, we have different vocal weights, sometimes referred to as the German fach. I'll go over them as well.
I can't believe I just now though about it. No one can really learn to efficiently do ANYTHING without first knowing WHAT is present in the throat,and how it works. DUH. So I'm going to add an anatomy section too.
