When singing how do you create vibrato?

Question:

When singing how do you create vibrato?

I can make a effect like it but I dont believe its the proper way. also, my voice register changes at about middle C where I cant do this effect any higher. (im a bass 1 to tenor 1)

Best Answer - Chosen by Asker: Vibrato comes naturally when you are ready for it. You have to be completely relaxed an singing properly, and then it just naturally comes. You can do some tricks to make it different once you get it, but until you get it where your singing and your just like 'o look at that i have vibrato' relax your voice completely when your singing. it wont be there on every note - so my advice is to do scales and see which notes it is easiest on - good luck your gonna do fine :-)
