Here are three examples of why so many people stop studying the violin (and other instruments) when confronted with this kind of a teacher. It's not so much what this teacher says that I find so very difficult to stomach, but how he communicates verbally and how he demonstrates his concepts musically. I imagine that there are other teachers like this loose in the musical world.
1. 2. 3.
(I know that #1 seems like a joke, but when you move on to #2 and #3, you will see that it is serious.)
When you have had enough, please go here for an example of how beautifully and effectively someone can use the internet to help people to learn about string playing and musicianship.
There is an elaborate discussion about these videos over at violinist.com. If you scroll down (or search for) "Nicholas Garibaldinos," you will come upon something far more disturbing than even the violinistic content of the video-violin-lessons: the "king" revealing himself in sentences that show he is either the product of a horribly deficient education, or that he feels that he is entitled to live far beyond the conventions of punctuation.
The discussion among the other literate violinists at the site is interesting reading, and Mr. Garibaldinos was kind to host a post by this "king".
