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.

Stage fright is my worst problem.

You have to have great passion, because to sing operatic music requires lots of work. I study for at least two hours every day. The voice is like an instrument and requires constant exercise.

To sing a duet together means sharing with someone both the pleasure and the responsibility of making music for an audience which is there to feel enjoyment through music.

When I sing for myself, I sing in a more free, athletic way. When I face an audience, there is always some fear that makes me put the brakes on a bit.

It is not Christian to go against someone. I am in favour of life.

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.
