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.
I don't like being called 'macho.' Macho basically means stupid and a real Italian man is not macho, he's smart. That's smart in both senses: elegant and clever.
What is certain is that singing is not merely modulating a song by means of the voice: we sing and we celebrate the beauty that we can grow and live every day. If you want to sing and give emotions to those who are listening, you must have something to tell through your singing; you have to use singing like an instrument to tell something.
The world is full of many beautiful voices; I will perform with many of them. I love women's voices.
