For a closer look at vibrato and so many other foundational techniques, take 5 days to learn my Violympic Theme with me: https://www.natesviolin.com/thevioly...

Here are the vibrato exercises I do every day. They come from Simon Fischer's wonderful book, Warming Up, which you can find here: http://www.simonfischeronline.com/war...

Fischer's exercises show that in the end, all vibrato is finger vibrato, since without flexibility in the fingers, you'd just be sliding your hand up and down the string! Therefore these four exercises work to develop that flexibility in slightly different ways.

Undoubtedly one or two of these exercises will feel more natural to you than the others, according to how you currently vibrate. But by practicing the four exercises daily, you will start to notice that your natural vibrato incorporates the different motions automatically.

I love that Fischer refuses to categorize his exercises as "wrist" or "arm" vibrato, or any other limiting terms! This is what the exercises have in common:

They focus on the main pitch but relax downward from there
There is only one impulse: "up", rather than two ("up, down")
The finger pressure comes out of the string as the pitch relaxes downward

In this video I demonstrate how to make each motion and then how to combine them for some rhythm practice with the metronome. Let me know how how Fischer's exercises work for you!
