gonfal asked: I'm thinking OP with the vibrato problem actually has a tension problem. My advice: sans violin, stand as comfortably as you can. Take your left hand, and touch your thumb to your second finger. Everything should feel loose. Take your right hand, your left hand shouldn't resist. Use RH and move your LH in vibrato motion, make sure you're not resisting. In slow motion with the violin, rest your LH third finger on the string, and relax your wrist back, and then move it back up. Check for tension.
