Well what have you tried so far.

When most people try to use vibrato, they wiggle their fingers in hopes that it sounds right. If you’re doing this, you’re wrong. You’ve got to use your wrist. Lightly move your fingers over the string.

It’s kind of hard for me to explain, sorry if I make no sense.

@KatetheGreat Well, I’ve tried moving it back and forth with one finger and eventually just looks like my hand is spazzing out.

@blueberry_kid Just make sure your hand is relaxed and don’t tense up, no matter what. Make sure you know where your pitch is changing and practice finding that right spot for a while. Over that spot, lightly move front and back. It’s not a dramatic movement, nor should you kill your fingers while doing so.

I play cello and I’ve tried to explain this the best that I could. It took me a few years to find my perfect vibrato. I know how you feel.

I’d also suggest you watch technique videos.

I seriously can’t find any! I looked on Youtube, but the way they do it is the way my teacher says not to.
