Useful and clear. Could you please say a word about why playing parallel to the bridge does not obtain the best sound or encourage a good bowing technique? (The string vibrates in a plane at right angles to the string; one might have thought that it would be best to provoque the vibration in the same sense).
I believe it's because (as he said) we have a natural tendency to angle the bow tip towards us; his technique sort of counter-acts this effect. If you are capable of maintaining a straight bow parallel to the bridge, it is probably better; I think he just uses this technique to balance our natural tendency. I am not sure; this is just my opinion
The movement of the string follows a Helmholtz motion. ccrma.stanford.edu/realsimple/travelingwaves/Helmholtz_Motion.html Maybe, by holding the bow a little bit less parallel, the ‘moving knot’ in this movement 1) slides merely under the hair instead of being cut off, or/and 2) although the area of the hair covering the string remains the same, the trajectory of the ‘knot’ is a tiny much longer than in a parallel holded bow.
Very nice lesson, Mr. Rachlin. Thank you.
thanks Julian
Thanks for the video! Can he also addresses the bow change at the tip as well??
Since the top of the bridge is curved , look at the bottom of the bridge. It will help the bow to be parallel to the bridge.

Galamian influence. Galamian says that when the bow is parallel to the bridge it produces an inferior sound compared when it is sligthly slanted
Genial!!!
how does the thumb move.,
Does anyone know WHY it is not optimal for the bow to be perfectly parallel?
