So I think I have down how to keep from getting that awful rusty-gate noise near the frog on an up bow. There are two ways to “hold up” the bow to keep it from pushing down on the string too hard. One can either lift the bow and hold it up with the hand (bad) or else just push down with the pinky and allow the bow to see-saw around the fulcrum of the center two fingers and thumb (good). For some reason, the mental image of carefully and smoothly skimming the skin off of a cup of pudding comes in handy.
Well, at least it seems that way to me. I can get a much more consistent sound (still a bit of a pitch waver, but far less than before, and no scrape) out of the bow clear up to the frog now, to the point where the edge of the frog catches on the string. It also feels less precarious and more precise to control the “weight” of the bow in that situation with the pinky than with the entire hand.
Switching directions still involves an unpleasant creak, though. I expect a bit of a “catch” when the bow switches direction, but I want to minimize it as much as possible. Perhaps being a pianist has spoiled me; I expect only musical sounds out of any instrument, and only the sounds I anticipate, and nothing else. I want that creak gone.
However, the scroll hand is still presenting me with challenges. Namely, my pinky refuses to get in on the game. While at my last lesson, my teacher did something to my scroll hand thumb to make it relax, and suddenly, my fingers just fell in line like baby ducks. Of course, I spent all night last night failing to reproduce this state of affairs, which has me a bit irked since I’m not up to wasting a week that I expected to use on scales doing CM over and over until I’m ready to scream because my pinky isn’t playing ball anymore. I’m going to have to do the scales with my teacher there, enough times to get it engrained into my head and hand a bit, so that I can reproduce the movements at home reliably. It’s either that, or else I waste another week, which isn’t acceptable.
I suspect that a lot of tomorrow will be taken up with me bullheadedly sawing away while trying to get my scroll hand to cooperate.
