C'mon, Fiddlerman.  how can you fix the smooth bow change when nobody on the planet agrees on how to fix the problem in the first place.  Here are the various explanations on what to do:

1. Slow speed + lighten bow pressure by whatever means you like in the final half centimeter of bow travel

2. Corner must be rounded by introducing a tiny loop (figure 8) horizontally or vertically

3. Its just finger flexibility, the fingers take care of the last bit of bow travel that was initiated by the arm.

These explanations are all crap.  #2 is nonsense because it implies turning around the object to go in the other direction like you would with a car.  You can't turn around the bow.  #3 is silly because it doesn't change anything and its a recipe for an speed up of the bow if nothing else.  #1 is academic lunacy.  Has anybody ever done speed and pressure excercises within a resolution of 1/2 centimeter? 

The bow change is as beginnerish as it gets.  Sevcik demands it on exercise 2 in beginners school and frankly its a mish mash of half baked theories in the books.

I think your response makes good sense FM. One accomplishes more when practicing with direction or purpose. Than aimlessly "practicing " just to say that you practiced for x -amount of hours but still have problems playing certain songs or passages. I was told it is more productive to work on breaking down the difficult spots until you can do it correctly. Then put everything together. Especially if you have limited practice time. I was never one that could just play anything correctly the first time through. A good friend of mine was a music professor at the UW-Madison,WI and he told me once that practice does not make perfect. But perfect practice makes perfect. I always appreciate and respect your experiences and insight FM!

Thanks.
