As an opera enthusiast, I am curious about vocal techniques of the past for opera singers, as we are in dire straits with modern singers. I am an amateur singer and I have been trying to figure out what has changed with vocal techniques. Since the most likely cause is problems with vocal training, I am hesitant to ask vocal coaches these questions.
I think that the most obvious quality lacking from modern male singers is squillo, of the kind that Corelli, del Monaco, or even Melchior had. I think this is what lets singers keep their voices even in dramatic roles, which is why a light voiced singer such as Pavarotti fared so well in big tenor roles. I was curious if anyone here had any ideas of how to vocally train to develop this lost trait, since it seems integral to any opera singer. Thanks for your time and your excellent reviews!
