A voice is very intimate. It's something of your own. So there's always this fear, because you feel naked. There's a fear of not reaching up to expectations. As you become more famous, people come and expect to hear something extraordinary, so you don't want to disappoint them. I feel this sense of responsibility.

For me, the most enjoyable type of singing is opera. It allows you to move, to wear a costume ... to do something with your body. When singing in concert you have to stand up in front of the audience, next to the conductor, which is less natural.

I have always tried to perform the music I love, and I think I am lucky because my preferences are often the ones of the public.

More people are listening to opera, and I'm happy - everybody must be given that opportunity.

The most widely criticised singers in the history of opera, Maria Callas and Franco Corelli, happen also to be the best singers. I am honoured for being part of their group.

Now I'm more sure and I feel myself more comfortable singing.

Because I practice often with my children at home.
