Stand up to play better 

I can't believe the degree to which you missed the whole point. You''re a physiotherapist! I am talking about the functionality of human movement. I do not raise the wrist: it's the MCP joint that rises, just as the hip joints rise as you get out of a chair. The standing action doesn't create stress, it frees the hand from stress. It gives you agency, activating the fingers for maximum viability, maximum control of the key. "Feeling the weight" creates stress. You are trying to relax but now the hand has a load to carry, it's stressed out. The fingers don't need to be subjected to that burden, they need to be freed from it - functionally! I like your post as it shows th difficultly many have in entertaining an approach that diverges from accepted canon. Anyway, I wish you luck treating the many cases of tendonitis and carpal tunnel syndrome in pianists following the weight release technique who inadvertently weaken the MCP joint, stressing the flexor tendons.

@@alanfraser2948 your medical ideas are a complete mess, as confusing as your biomechanics comparing the MPC joint with the hip ones (quite fun though). Anyway I don’t love divagating from one or another joint, I was just searching some ideas by curiosity. Love practical and clear language, I’m a medical caregiver not a mystic keyboard wizard

Did you check out the playlist with the other videos? It goes into a bit more detail but at the end of the day there is no one size fits all solution as everyone's a bit different. There is a real danger of people giving bad advice in regards to technique, but at the same time if people can not create and share what they believe to be innovations on technique then music as a whole would not progress. With that said, these teachings are like any other, they are but a set of rules which you may, or may not apply. The choice is up to you. I would use these concepts where it makes sense and to the degree in which it works for me, using my own critical thinking to come to that conclusion.

very well put, Rob, I heartily agree...one size does not fit all. I have tried to present these ideas in a way which offers maximum flexibility to those who want to entertain them. in other words, try to find your own "size" amongst all the possible interpretations of what this structural-functional approach means
