I find that if I am ascending a scale I can manage by anchoring the edge of my palm against the bridge and span all the strings decently. When I am descending, however, in an attempt to get the same speed as I ascend, I have to pull my hand up with my shoulder in order to smooth things out and accelerate more. My hand is basically in float mode at this point.
Does anyone else need to do this? Is this problematic if I try to develop this? I’ve run into so many dead ends technique-wise over the years I am trying to avoid that now.
