"I see. It seemed so strange that increasing the weight that the arm is already exerting on the arch can actually improve shoulder relaxation."
Ah, that's the odd thing. Although that weight makes it far easier to work the hand, it also makes the shoulder inclined to withold a little more, instead of release all the weight into total collapse. If you find a comfortable way to do that, it makes it easier for the shoulder to 'float in regular playing. It was only through doing that exercise that I came to realise that shoulders can easily be overrelaxed as well as held stiff. It made me differentiate properly- instead of go between held or relaxed. I was forced to find a comfortable way that involves resisting weight, without stiffening or removing all slack. I can feel way more possibilities now, rather than simply 'held' or 'released'.
If you can find a functional balance when your arm is a little heavier, it makes it vastly easier to do the same when you play normally. I wouldn't advise playing with the weights (unless you have a pretty effortless arch and finger action) , but I'd definitely advise practising a variety of slow arm movements with a kg wrist weight (or just hold a plate of a kg or two). Raising the elbows away from your sides like in a chicken impersonation is very good. I think this involves the exact muscles that I discovered myself to have underused. I feel like I need a slight space in the armpit. I'd actually gone too far away from 'elbow out'. When the shoulder releases too fully, the elbow gets stuck too close into the body.
"There are 2 options....either I straighten my 2nd,3rd and 4th fingers(to avoid the black keys) thus my 5th also straightens. Either keep the fingers curled in the arch shape and try to get the 4th on a trajectory between the black keys before it even reaches their top. I think the last option is far too complicated. Maybe I will post a clip to make things clearer."
Yeah, I can't quite picture it, to be honest. A video would certainly help. However, I'd definitely start with an isolated 5th finger pull and then move to an exaggerated grasp (starting totally flat, but progressing upward to a big arch) and practise standing on that. I can't see any reason why the fourth would sound, unless you have excess downward movement. Unless you have problems with your fourth when playing the fifth alone, it suggests to me that there's too much collapsing and not enough active motion from the fingers. Are the fourth and fifth collapsing downward as a single unit? Is this what you mean by rotation? I can't understand what rotation could really add here. I'd think of lifting away from the keys, not collapsing outward.
