What works well for you?
Most of my work in this stage is s-u-p-e-r-s-l-o-w practice with focus on touch and tone, nothing like a magic "interpretation" or anything. The music usually plays itself rather well without artificial tricks if you do what you have to do.
Out of curiosity, are both of you concert pianists? Your posts and tips here have truly given me wonderful advice. It's ok .... I won't ask your names .. it is just that whenever i read your posts, I notice that your insights are high calibre.
For the "grounding", I take the pieces by storm. This means page by page until they are more or less ready to be worked on artistically. Any mechanical "difficulties" that hamper the flow are dealt with without delay with zero tolerance in terms of hesitation etc. I go on doing this (on that same first day) just as long as it takes
does this mean you might spend days practicing one piece only and foregoing all other pieces?
No. Not at the stage you quoted. If I cannot get the basics (the notes, the mechanics and all requirements in terms of tempo) of a piece ready within a couple of hours, then the game is not worth the candle, and I will rather put such a piece aside and take something else.The other stage, though, (working slowly on touch and tone as soon as I know my pieces thoroughly) is different. I may indeed work the whole day on part of 1 piece only, and leave the rest of my repertoire alone.
So how do you work on things like, say, the dante sonata or Beethoven op 110/101? Do you manage to play them through, in a good tempo, a few hours after your first look?
The "grounding" (first layer of paint) as I called it above, yes. That is the benefit for me personally of developing the mechanics/motorics of piano technique not per each piece, but separately, in special books on technical formulas,
And loads and loads of Bach, I assume?
