I hear a lot of pitch and sound techniques, based on your "throat", but I don't think you have something that can move in your throat. At least, my throat is my throat, air passes through it, and that's it! I really don't get it. Btw, your diaphragm, where is that exactly? Do you use any of the techniques with your throat in daily actions? If so, which ones, so I know what to do..
