Of course the most difficult thing on the violin is always intonation. The second one is rhythm. If you play in tune, in time with a good sound that's already high level. Those three are the main things.

Well, rhythm is 90 percent of the interpretation.

I don't have favourites, I think, when you play, you have to be like a prostitute, you have to love the piece you are playing. Even if you don't like it, you have to play it as if you would like it. Then you are a good interpreter.

You have to do a lot of listening, you don't just learn out of yourself.

It would be easier to say, what was the difference in style from many years ago. Many years ago, the old violinists, they also had a good technique, they were not tonally as good.

Every violinist has a different style, so it's important to be able to recognise their styles. You don't have to like everyone's style but you have to know these styles.

A specialist is someone who does everything else worse.
