And what classical music does best and must always do more, is to show this kind of transformation of moods, to show a very wide psychological voyage. And I think that's something that we as classical musicians have underestimated.

Pop music, which I deeply admire and wish I could play better than I can, is based on expressing one mood, one feeling at a time. Classical music is by its very nature involved with different kinds of music, constantly transforming one another, which is more akin to the way our experience of life really is.

Part of my big message with all this is that if you are alive, you know all you need to know about the message of classical music, because more than any other music, it is about the way life really is.

When I was a kid, three years old, I couldn't walk by the piano without reaching up and trying to play a few notes on it. There are kids who are just drawn to listening to music and dancing to it and trying to conduct.

But a large symphony orchestra basically is a repertory company and it has a very enormous repertoire and it is important for the performers to be able to know how to shift focus so that they instantly become part of the sound world that a particular repertoire demands.

If you're alive, you have all the experience necessary to understand classical music.

The world changes when there's music in it.
