I agree. It does have to do with the player, BUT, the bow is an integral part of it as I recently found out. I bought my violin and it came with a bow...well that's what they were passing it off as anyway. It was garbage. I purchased an Academy carbon fiber for $95. It was good...for a while. As I started to develop my ear, I noticed that it wasn't up to par anymore for me. So last week i began mu pursuit for a new one. I tried the Mark Wood "Turbow" ($116), also carbon fiber and the Coda Diamond NX ($355). Both were great bows. Both had excellent balance. I sooooo wanted the Turbow to be the one, but Coda beat it out by only a fraction and it was over tonal quality. SO this morning I purchased the Coda. It hurt, but I am glad I did it.
I also noticed that the shoulder rest seems to be a big factor in my playing ability. I started with an Everrest...it was ok, but I upgraded this week to the Bon Musica. Little pricey, but the difference in my playing ability was night and day! So, for me personally, I think I now have the right combination to further my fiddle education.
BTW, hi all, I am new. Just joined. Glad to be here.
