How it affects to my playing if I have very bow hair
My bow hair has become thinner. How it affects to my violin playing? I found it's hard to bow straight, but I don't know is that 'cause I have too very hair?
Most players get their bows rehaired at least once a year. I do too, even though I'm kind of skeptical about whether it's necessary. But in your case, you should do it.
A bow will play and feel differently if too many hairs have broken and are missing, and if much of the missing hair is on one side, it can eventually warp the bow. Most players will have their bows rehaired long before this point.
Carlos has said all I can on this matter without knowing more about the exact condition of the bow or the player's skill. My website left the internet about 6 years ago after I ended my business and let a different "Victor Technology" have my URL.
I my opinion when you start skating on thinning bow hair you probably compensate adversely with your bowing and need a re-hair. You will be glad you did.
