I tell students, 'If you are learning from YouTube I almost don't want to teach you because what you learn from YouTube it takes 10 times as long to unlearn.' They do an approximation of the centre of the note, an approximation of the interpretation, a cloned version.

I used to suffer from a lot of regret while touring. Regret at having to leave certain places, people and situations, or just a beautiful day.

When I'm alone at home, I really prefer to listen to Wagner's orchestral music rather than any vocal music. I find it illuminating not to have to pay attention to voices in the recordings.

I'm completely in charge of my own life now. Sometimes there's no one there to slap me on the hand and say: 'Stop being so bullish and bossy,' and things like that.
