It's study; it's Nature. I'm doing nothing special, you know. Even "Lucia", "Anna Bolena", "Puritani", all these operas were created for one type of soprano, the type that sang "Norma", "Fidelio", which was Malibran of course. And a funny coincidence last year, I was singing "Anna Bolena" and "Sonnambula", same months and the same distance of time as Giuditta Pasta had sung in the nineteenth century... So I'm really not doing anything extraordinary. You wouldn't ask a pianist to be able to play everything; he to. This is Nature and also because I had a wonderful teacher, the old kind of teaching methods... I was a very heavy voice, that is my nature, a dark voice shall we call it, and I was always kept on the light side. She always trained me to keep my voice limber.
