Cheers for the feedback. I'll go through a few points:
"That action-reaction theory is very clear for me but I can't understand where to aim at when trying to perceive the reaction force? Action means, from what Alan has taught me, a backward finger pulling. Reaction means...? The forward motion felt in the elbow and shoulder joint? I think this is the most difficult part one experiences when doing these kind of perception drills. It is difficult to take the reaction into consideration because you don't create it directly. The reaction is being created when you play."
Basically, the meaning of "action" is more specific in physics. Alan refers to actions in the general sense of activities. The action in physics is the specific force and direction. Strictly speaking, the inside of the finger is a whole string of actions and reaction- as muscles and tendons etc. pull on bones that drag others in a whole chain. Movement of the finger is a reaction itself- that causes an action upon the key. Anyway, rather than concern ourselves with every component, however, we are probably better off looking mianly at the resultant whole that acts upon the key and the reaction that occurs.
The "reaction" is often odd, because strictly speaking it's the follow-up- yet it's often easier to judge from the reaction than the action. For example, in the walking thing mentioned- where thinking of the downward action tends to create heaviness but feeling the upward reaction lightens things. I'd think the same way when doing a knuckle action. It's often good to judge from the reaction that pulls the knuckle higher- rather than the action that pushes the key down. Two ways of thinking give a real point of focus and can have surprisingly different results- considering that reaction is caused directly by the action. It's a good way of showing up faults in the perception, before trying to get the two ways of thinking to produce something similar. If our perceptions are accurate, there should be no difference.
Regarding the arm however, I don't think you should have any expectations about how it should respond to reactions to the hand's action. I think the whole point about how the arm operates as your shock absorber is that it MUST be passive. You can't be to make the arm respond to reactions in a specific way. You can only make it loose and movable enough to LET it be affected.
"The exercise with the pencil was also helpful. I think that one year ago when I was almost an absolute beginner I tried to play similar to your first example - moving the whole pencil down. I think that resembles a hand without finger action. Now my playing resembles your second example when you lower the end (actually the tip) of the pencil."
To clarify in this one, the direction of action/reaction keeps changing. I may make a slight addition to that post at some point. I believe the action should be approximately 90 degrees to the end of the pencil- so, as it's levered up the direction is constantly changing. The reaction here is what pulls you forwards and up, around the point of contact.
Also, I'll be involving another type of movement that is a little simpler than this one. Both have many uses and I still firmly believe in the style of movement described with the pencil. However, I'm also using a great deal more of one where the action is more forwards than backwards now- following some lessons with Alan.
"My fingers are active. The wrist breathes. I feel weight behind the wrist but I know that it is not the appropriate kind of weight. I even assume that this "weight" I feel when I'm playing is sometimes the muscular tension you mentioned when you talked about "seeking gravity" instead of letting gravity act. Due to this the fingers sometimes slip off the keys as there is not enough arm weight to hold them stable. I don't know if this is a matter of practice or I should just try to sharp my senses for the moment."
It sounds like you're thinking too much from the wrong end. Everything needs to move around the fingertip. Try thinking from that end and working backwards. That's the only point that doesn't move- relative to the key. You may not necessarily need more "weight" in the sense that you would want to feel it pressing down hard through the key. Remember that release of weight primarily makes the arm hang back. If it creates a big downforce directly, it's probably muscular pressure, not weight. It's more about observation of what weight does upon release- rather than the sense of trying to make weight act down through the hand. Also, try making the arm feel ultra light sometimes and just observe what it's like to move the finger and whole arm around a stationary fingertip. These can be practised on a tabletop very usefully. It's basically about getting the whole arm to respond around the finger's point of contact- rather than the fight the reaction force.
Also, does the finger bend when you slip? Maybe the action is coming too much from two lesser joints rather than the knuckle? The type of action where these straighten slightly may be useful to you. When the knuckles are ultra-high, it's sometimes hard not to slip with a pure "pull". Maybe a trace of straightening is the missing link?
Hopefully I'll be uploading a number of videos of direct exercises for the hand before too long. Although quite a few of my posts have been about generic guiding principles, the next few will be getting straight into the heart of applying these principles to very specific movements in the hand. I have quite a few exercises planned out that are different to Alan's in specifics and which will be described in somewhat different ways- but with much the same goals in mind.
