Hi. I just have a technical problem: upon playing on a "new" piano for the first time on a stage, my fingers get really wobbly and lose dexterity (the structure of my hand weakens and falls much more easily). It seems like I need some time to get "used" to the piano keys, pedals, etc. As such, the beginning of my performances are often technically flawed and not as brilliant as they should be.
The problem is gradually diminishing. For me, I just "command" my fingers what to do, and my nerve and muscle cells do the rest.
Are there any tricks or ways to immediately "adjust" to new pianos when performing? Because of the brain-muscle connection, I am going to start sleeping more the weeks before a performance and begin eating healthier as well. Should I also just practice on more than 3+ pianos to get a dynamic feel? Should I practice/finger-tap more? What are your suggestions, and do you have this problem? What are your experiences with this, if you've had it? (It just seems like I'm the only one afflicted with this--even five-year-olds have that control on any piano they perform on!)
Thank you for reading!
