These are great.  Yeah, they are quite archaic by todays standards but I do like some of the emphasis he places on the importance of correct posture and most important, limbering up the body so that it is not stiff or rigid but movements flow in a fluid manner and the motion is loose and flowing. I think this is important and can never be overly emphasized. it reflects in my own playing. If I am tense, rigid, worried about something, the music comes out sounding tense,rigid, and very mechanical and not very pleasant.  The more I am relaxed and limber , the music comes out much more smooth, flowing and more pleasant sounding... although in my case still in need of much improvement. 

A also love the way these were filmed, rather than taped  or digitally recorded.  They have that classic colour and sound deterioration, and appearance of old 16mm motion picture film that has been sitting around for decades.  Reminds me of the old ephemeral films we were often shown in school. Glad that someone had the sense to digitize these violin videos and archive them thus preserving them onward to the future.

Its also wonderful that people like Fiddlerman are making great tutorial videos nowadays to help people learn in the present and future.
