Ronde happens to be a world class pianist in my estimation.
That's very nice of you to say so, but it's not really true. I've worked hard, but remain a bit untidy at times. However, my background is vaguely relevant to my next point.
Do you guys really think that so many great artists play the Schumann PC because history told them to, rather than because they really, really like it? If they didn't wouldn't they just play the many other pieces that history has deemed worthy that they find more agreeable?
Not talking about the Schumann concerto here, more about canonical repertoire. I believe that people who become pianists through the conventional route are subtly conditioned and directed towards certain, more or less fixed, notions about what the greatest music is. It is very rare, I suspect, that academia encourages scrutiny of its sacred cows and asks pertinent questions like 'WHY are the Liszt etudes greater than the Liapunov etudes?' or even, heaven forfend, 'why is the Schumann concerto greater than the Henselt?'. The result is a rather ossified construction of what is 'great music'. Perhaps because my training has been, to put it mildly, unconventional my judgments are made according to my own artistic credo. It is of course also susceptible to its own inherent biases, but at least I'm aware they exist. I think there is an insidious intellectual laziness in blithely accepting 'received wisdom', not of course that we all have time to sit around re-evaluating the full corpus of piano literature.
