To start this off I don't have any ambitions to become a "proper" classical bass player, but I do want to learn good and healthy technique with the bow. Living in Vienna the school that virtually everyone here learns from is Ludwig Streicher "Mein Musizieren auf dem Kontrabass" which shows something that my teacher has made me put attention towards: the bowhand should "flow" when you switch between upbow and downbow. When you push the bow on the upbow the wrist kind of collapses to the right, on the downbow it flows in the opposite direction when you pull the bow. This should make the entire motion more fluent apparently. That said, my teacher also mentioned that there are also players who play with a fairly locked/stiff wrist (as I have been doing up until now) and that this can work out too. My question is: is the "locked" wrist considered bad technique or simply different? I feel like I lose control of the bow fairly quickly when I'm trying to do the fluent motion, I can't maintain proper pressure on the strings that way. That might just be a matter of getting used to it but maybe the locked wrist has other advantages that I haven't heard about yet and it's just a different approach. I'm definitely interested in other peoples opinion on this outside of Vienna since it's so easy to get stuck in the mindset that the local school of thought is the only correct one.
