I think I have a pretty good voice but when I do long notes, they sound choppy because I don't not know how to add vibrato to my voice. Please help me achieve vibrato! Thank you so much!

If your tongue is not positioned properly (too much backward or too much forward) you won't get any vibrato. You can achieve a perfectle relaxed tongue by saying the sounds: "The" or "Gna" than let the tongue rest its tip slightly on the top of your front teeth. It should always go back to that position during enunciation. It you do it correctly, you will see a "U" shape appear in the back of your tongue. Let me know if that helps!

also, too much pressure from your support, and too much air can cause tension and prevent vibrato from happening. Relax when your sing!

i first started off learning vibrato by humming.
Do some trills whilst humming very lightly... until eventually you start feeling it happen without conciously changing the pitch....
then keep gradually building on it....from low full voice notes to high full vice notes.

thanks so much

There is something I need to ask. Basically, when I do vibrato, I use what I think is stomach vibrato with a slight pitch vibrato (or not so slight in other styles). Is it normal that my jaw and the muscles underneath it are pulsating? Wherever I can use full voice (chest plus the lowest notes of the head voice) it's mostly the stomach, the jaw is hardly moving but when I use falsetto or even more so when I use reinforced falsetto, the jaw is *really* pulsating a lot. It doesn't sound bad at all but I find that when it's mostly the jaw and the muscles there that are pulsating, I have a limit on the speed of my vibrato that isn't that high. Is this normal?
