hand position

I agree on the "natural" position of the hand.

thank you Maestro!! in fact I also think that positioning the hand on the metacarpus by forcing it might look good, but it doesn't turn out to be functional when playing. I think the matter of the hand with prominent knuckles depends from person to person, meaning there are pianists whose hands have these more prominently than others.

It depends on the length of the hand. The important thing is that the setting is natural. Since I have a very large hand, I keep my fingers highly arched to maintain a firm and comfortable position on the keyboard. By stretching my hand more, I would end up inside the black keys. In this way, however, I strike the key in the area near the black keys and therefore I can easily get 'into' the keyboard and onto the black keys. A small hand, probably to strike the same point, must stretch the fingers slightly and consequently the knuckles descend. I believe that in both cases, the important thing is to have a well-based hand thanks to the musculature of the palm that gives shape to the hand.

"In this way, however, I strike the key in the area near the black keys and therefore I manage to easily get 'inside' the keyboard and onto the black keys"...could you explain yourself better? are you perhaps trying to tell me that there is a spot on the key where it is better to play? hi thanks

It is not a question of where it is convenient to play, there isn't exactly one specific point where you must strike the key; I would say more of a certain area. Not too far in towards the black keys but not too far out either, let's say at the base of the black keys, so that they are easily reachable without having to make unnatural movements. Naturalness and hand position depend largely on the anatomy of the hand we are considering. Small hands, by necessity, cannot have the same position as large hands; this is what I am referring to. A natural position for a large hand is not necessarily the same for someone with a small hand. Rather than position, however, it would be more appropriate to speak of "behaviors" when faced with the various difficulties encountered in piano technique. Under certain stresses, a large hand behaves differently from a small one. In close-range playing, the small hand is certainly advantaged; in wide stretches (from sixths onwards), I would say the large hand enjoys greater stability and ease. As you well understand, every situation depends not only on the pianist's ability but also on their hand. Pianists with small hands must face more difficulties, especially when they encounter virtuoso composers.
