Hello! So I'm not going to have any classes till next year and I hav a little (big) problem. My bowing is jumpy, I can't find a better way to describe it. Specially when I'm pulling the bow, the tip seems to jump on the string. I've tried several things to correct it: Loosen the bow hair, apply as less weight on the bow as possible, changing the angle of the bow. All seem to work partially but my arco is still jumpy. This is driving me mad because I can read and understand exercises but cannot play them because of the bow. Any suggestions?
