One of the problems I had when I first tried adding vibrato was that, as I was gripping the fiddle too tightly, I was moving the whole instrument back and forth rather than rocking the finger on the fingerboard. A tip I picked up at a workshop was to stand close to and facing a wall. With the scroll resting against the wall, the fiddle is trapped (gently) between the chin and the wall, keeping it still. Well adjusted chin and shoulder rests will support the fiddle and allow the left hand to be more relaxed.

Even after following these tips, vibrato is still a technique I am having to work on.
