I know that my passion is for opera, but sometimes I like also to sing songs, because there are many beautiful melodies.

I started as a lyrical singer. But it was through the pop universe that I reached international fame.

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.

It is the uninvolved parent who has to resort to strictness.

The voice is something very mysterious. It's difficult to say what is inside a voice that moves people.

Listen to what others tell you about your voice. If you're only singing to please yourself, you might as well just sing under the shower. But if you're singing for others, you are reliant on them to ask you to sing.

Every audience has its character; I like America - they love me. I suffer from stage fright, but in America not so much.
