Thank you. I was rotating my wrist thinking that would help long term dexterity. How do I know the context when to rotate wrists and when not to?
I'd use wrist rotation as and when it works for what I'm looking to achieve - and I don't think of using it consciously. Like all movements to do with piano playing, what you want is efficient and controlled actions that produce the sounds you want, without causing unnecessary tension that might lead to injuries. Very often, it's down to having spent sufficient time and having experience of playing a wide range of pianistic figuration and textures and styles, and - of course - being fluent with basic techniques (scales & arpeggios etc).
So, I'd use wrist rotation when playing broken octaves and tremolos - because the wrist instinctively rotates when you play them. But I wouldn't when playing trills with 2-3, though I might if playing loud trills with 1-3.
When playing lightly & delicately - as you'd need to in your piece -, you'd normally just use finger movements with 1-2-3. If you find that 1-2-4 and 1-2-5 benefits from wrist rotation, by all means use it. But never use a particular movement just because you've read - or been told - somewhere (e.g. from Taubman's disciples) that you "must" always, unless it actually works for you.....
