I just came up with an interesting exercise, regarding release and weight. Try starting on a slumped thumb against the keybed and lighten the arm enough to push yourself away from it- until the thumb is fully extended. At this point, feel closer to the feeling that that the arm "floating"- but be sure that the elbow and shoulder are hanging back, to pull out any kinks in the chain eg. an angled wrist. The pressure between the thumb and keybed should now be fairly low. The shoulder supports quite a lot here, and it may even be perceived as if no weight is resting through the thumb. There's just a sense of thumb reaching all the way out from a "floating" arm.
At this point, take your hand away and then place your thumb against the wood above the keys and push yourself away from it. Stay lightly in contact with the vertical surface, and try to relax (again letting the elbow hang back) Can you feel the difference between the two? In the latter, the shoulder has to support the arm 100%. Try to relax as much as you can- but you will likely perceive a very slight uneasiness due to the total absence of support at the thumb end. Try as you might, the arm must work harder. It wouldn't be a nice position to stay in for ages. If you go back to contacting a key at the keybed with the thumb, it's nowhere near the feeling of letting 100% of weight rest on the thumb and may well feel more like floating than "resting" weight downwards. However, there's a very significant difference in the sensation, compared to when you are necessarily supporting all of the arm's weight at the shoulder. Small as the sense of weight may be against the keybed, there are many key muscles (in the arm) that are able to release their level of supporting effort, when the thumb has an actual point of support. While the idea of "supporting the full weight of your arm" on the hand is a huge hyperbole, I think the difference between these two states helps to illustrate the significance of a vastly lesser "letting go".
I think this is a very useful observation to make. While the arm may still be thought of as if floating while a finger is contacting the keybed (to promote a sense of lightness), it clarifies that there is indeed a notable difference between any illusion of actually supporting 100% at the shoulder and the reality of a state where the arm is allowed to spread balance between two points. The perception of the difference between the two states may sometimes be small to the point of being unnoticed, but the extra ease that comes from having even light contact with a keybed is extremely significant. I think this exercise reveals that level of significance. I don't think you're capitalising on this difference. Small as the release may be, it needs to happen for full comfort. I'd try spending quite a lot of time going back and forth and comparing these two states of balance, until the slight differences become clear.
