National Piano Schools

[wojcia3333]

Hi everybody, I am doing at the moment Doctorate on the current state of National Piano Schools of teaching and performing (Russian, German, French etc.). I would like to hear some of your opinions on few things:

Do you think that National Piano Schools exist in the 21st century (If yes, in what way, what might be their characteristic features)?
Can you tell just by listening to someone, what are the origins of a performer's education (eg. is he or she Russian pianist or a teacher that represents eg. German style of teaching)?
How did the situation of National Piano Schools changed in the 20th and 21st century?

I am open to any discussion.

Regards,

wojtek

ps. I have started this thread in the section for teachers also as I am looking at opinions of anybody who might be interrested.
