My decades old copy of Opus 821 by Czerny. Still on the piano.
When I want to work on my tone, I go here. When I want to work on the different physical moves required in piano performance I go here.
This work covers all the keys in very short 8 measure exercises. I'm able to work on finger independence, arm weight, rotation, octaves, staccato, legato, portato, drop, thrust, dynamics, balance, and tone.
Last weekend I attended the National Ballet of Canada's performance of "etudes". It is a 45 minute ballet of bar moves and set pieces to the etudes of Czerny. It was fun to recognize many of the pieces. It was instructive to hear the music interpreted by the dancers.

You've got to learn your instrument. Then, you practice, practice, practice. And then, when you finally get up there on the bandstand, forget all that and just wail.
