Hmm, surprised there's no discussion on this one...I've never been to a masterclass, so this video was very interesting. Reminds me of my piano teacher I had over the past few summers when I was back home from university. I'd just show up with whatever pieces I was learning, I'd play, she'd give it a sight-read and then give the best advice, sometimes hard to follow, sometimes the language a bit too flowerly lol. In a few parts some of the way he expresses ideas is quite funny. Even he knows he's not making sense, but it's hard to put musical expression into words.
I thought it was kinda encouraging too, to see that here are students playing (to me anyway) pretty much perfectly, but there's still a lot more to learn and explore. That sort of reminds me to not be to hard on myself because I have a lonnnnggggg way to go before I can even begin playing any of the pieces done in the masterclass!
Strange though that he says he never learned Ondine...
