Tuning the violin is difficult. This info is pretty in-depth. There are other videos on Youtube that are better primers for the absolute beginner. Part one in series.
PLEASE NOTE!!! These motions are natural and will help free you from tension. Very small amounts of the motion described here can be added to your playing but please don't try to play like this all of the time. It's way too much motion and will distract your audience! Also, any violin motion...

Two ways of learning this bow stroke. The second way is from the teaching of Paul Rolland (as taught to me by Richard Fuchs, Professor at the University of Northern Colorado).
