Another little question, if I may? I have done a search but the question doesn't appear to be anywhere else. I am teaching myself violin with the aid of books and youtube videos (particularly those of ProfessorV - AKA Tom Ehle) and have a query regarding wrist vibrato. I've gone through the exercises to concentrate motion on the wrist and hand only, but find that when I move this to the instrument, my forearm moves, although it is not the origin of the movement. I find it intensifies the faster I do the movement. Will this stop as my muscle develops or it is a technique issue that I should correct? Or indeed am I being too fenicky about it - a guy I know who finished violin with a Grade 8 Distinction, many years ago, appeared not to know there was a difference between arm and wrist vibrato, as long as the sound came out correctly.
