Train separation, not strain
Independence improves when one finger can move without pulling the whole hand out of shape.
Finger independence at the piano is not isolated finger force. It is the ability to keep the hand organized while one finger moves, the pulse stays steady, and the tone remains even enough to repeat the same assignment cleanly.
Independence improves when one finger can move without pulling the whole hand out of shape.
Slow work makes weaker transitions obvious before speed turns them into compensation.
The goal is a result that holds across several runs, not one unusually good pass.
Work on one short Hanon cell or one finger transition instead of the entire pattern.
Choose a speed where you can hear unevenness and feel unnecessary effort immediately.
Keep the pattern fixed long enough to decide whether control is becoming established or only occasional.
