I think anybody who's willing to really sink their teeth into a work like the Hammerklavier, which is a very interesting, different experience, should look instead at something like the Sonata by Paul Dukas, which, in my opinion, is a real marvel.

It's the vision of the composer that we have to determine, and not the absolute mathematical adherence of the score. In my experience, there have been occasions where I feel that a composer has not notated something as they meant to have it represented.

My father was a very good amateur pianist, and he had a collection of books on technique. One of the things he had was a small volume of exercises by Rudolf Ganz, in which Ganz mentions the pedagogical work of the Swiss composer, Émile-Robert Blanchet, who wrote a ton of polyphonic exercises for one-hand. These exercises were a great help for finger independence, which I acquired early on. This might have given me somewhat of an edge, a facility to be able to knock any obstacle that was in my way.

To be perfectly honest, I was never really aware that I had any special abilities. When you have what you have, you don't really think about what you don't have; you simply work with what you have.

I never considered myself more able than anybody because I had problems just like anybody else. When I practiced, I solved problems, like any of my fellow students. I looked at my own work, and looked ahead, with blinders, almost.

There's a substantial portion of my recorded repertoire that was learned for the recording sessions, and then basically forgotten. I wouldn't say it's the majority, but it's a fairly good chunk of it.

I don't listen to recordings very much now, to be perfectly honest. I listened to them a lot when I was younger.
