Anyways, my questions/concerns are these: I can't play through this consistently like I want to. I know it takes time due to it's difficulty.. and there are other factors. It's always cold in my house so my fingers suffer from that.. and a piano tuner has said my piano hasn't been 'regulated' in way too long, so apparently he says certain keys won't repeat quick enough or play pianissimo consistently due to the felt and hammers or something like that. We're gonna get that looked at. However..
