I'm most impressed by the Russian writers, so I love reading the works of Tolstoy and Dostoyevsky. Another author who has informed the way I think is the French philosopher, Blaise Pascal.
Music is an art that goes well beyond science. Proof can be found in the huge amount of studies that have been carried out throughout the world based on music-therapy and the important results achieved.
Because, in opera, I have to sing for people that are very far from me, instead of, when I sing a song, I try to imagine to sing like in an ear of a child.
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.
