That's exactly what is happening with my vibrato it's good when I do it slow but falls apart when I try to speed up I'll definitely start doing the 4s then 6s thanks
What if you can't vibrate at all 😛 Tried your method for learning but teacher says I am just rotating my wrist and it isn't real vibrato. But by trying to move my arm not my wrist there's barely any change in pitch at all. I would be quite happy having a hummingbird vibrato lol. Hopefully it will click soon
Took me a year to get it. Then one day it just kind of clicked. Something that help was practicing on my arm (left and around right arm). Start loose and use left arm not wrist like your teacher suggested.
Update: I got it! It isn't even and I can't keep going on the upper 1/3 of the bow but I have something to work with now. I had a lot of trouble feeling the difference between the whole arm moving and just the wrist moving. But what helped was practicing putting my 2nd finger down in a table top, and wobbling the whole arm back and forth and paying attention to how that feels in the arm. It will look similar to the right arm of a good cellist playing short notes with the elbow being a hinge and the upper and forearm going opposite directions with each wobble, but with the elbow moving (in space) less (but still moving). If you are old or overweight you can try and get a feeling of your upper arm flapping a bit 😂 Then try and get the same feeling on the side of your cello's body and in between the strings. Then to actually vibrate, you rotate the arm BUT still have the feeling of your upper arm flapping to make sure you aren't just rotating the wrist. If you can put a mirror on your left side you can see if you are moving your whole arm or just the wrist, and if the wrist quickly stop that.
The problem is the thumb is sticking to the back of the fingerboard. Try keeping the thumb completely loose- not even touching at all or just lightly touching. The other problem is the motion doesn’t come from rotating the wrist or even flexible fingers. It should come from the forearm. Slide up and down the fingerboard in big motions, then gradually get smaller and stick to one note.
