Sorry. I only post now because... well. VACATION AT LAST!!!
What can I pass on, I think its nothing that no one already knows.
Practice as much as you can.
Never practice with a cold heart and a hot head. Think and feel. Volodos and Lupu started very late. Especially Volodos. Galina was also a child prodigy, although she chose to teach. For her, there are absolutely no technical problems. Al technique is in your head. Like Volodos said. You need a lot of imagination. The way she says it is: There are no hard things on the piano. (Technically at least). Any hard passage can be broken down int doing a lot of easy things at once or really fast one after another. In other words, you have to train your mind to think as fast as possible and your ears to hear as fast and as cantabile as possible. Not your fingers to play as fast as possible. That way, your technique will not only be complete, but it will not be empty. Its easy to play a chromatic scale very fast. Its very hard to hear every single note in that scale, regulate the quality with which you play it and correctly intonate the conection between every note. So always ALWAYS break up everything into the smallest possible units that your mind can handle. Thats basically all she tells you about technique. Hear everything you do, and play in the most natural way possible. And always have a lot of enthusiasm for what you play.
What she tells you cant really be resumed into one thing. The only thing I can say is that she always makes you love playing, even if she is so strict.
