hiro: 1) Ayu herself called it "fake japanese", don't worry, we didn't make it up to make fun of her and it IS fake. It's over the top the way westerners expect "japanese" to look.
2) Actually there IS a right way to do vibrato. It's in the diaphragm (which is also the right way to sing, to maximize output of vocals while minimizing the output of air)... the throat is preferable also. It's only correct for an opera singer to use their mouth, and only when they're still training to project their voices better so that they can use the diaphragm or throat to do it. Using the mouth or tongue to do vibrato is looked down on by professional singers (not pop singers or singer/songwriters or rock singers or performers, i mean professional SINGERS. Like church/opera singers); it's kinda like doing girly push-ups.
