You've just illustrated by your support of Madam Fleming's exercice that your knowledge of the voice is as lacking as hers. Viva is indeed more knowledgeable than a great deal of current operatic singers, for if it were the opposite, then the level of singing would be much higher.
And what knowledge would enable you to discredit Viva's comments? You have shown time and time again you profound disinterest for historical recordings, which are the main gateway into understanding and appreciating the grand operatic tradition. So many times on this forum have you expressed scorn towards members who appreciate historical recordings, saying that the sound is so bad one cannot hear a thing. Well, such willfull ignorance more than disqualifies you from mocking and arrogantly putting down members who's knowledge elevate this forum.
And by the way, it has nothing to do with style, but with the natural working of the vocal organ. There is a reason why barely any singers can bring justice to Wagner, Verdi, Bellini, Puccini, Mascagni, Berlioz, Bizet and so many other great composers. The teaching is wrong, and Madam Fleming is one exemple out of many of the misinformation and stupidity being passed down to young singers who are only willing to learn.
And now David, instead of accusing us of nostalgia, why don't you show us examples of modern singers who can comapre to the likes of Hans Reinmar, Gino Bechi, Lina Bruna-Rasa, Ebe Stignani, Gotthelf Pistor, Alexander Kipnis, Emmanuel List, Mario del Monaco, Franco Corelli, Tito Schipa, Beniamino Gigli, Enrico Caruso, Rosa Ponselle, Maria Callas, Renata Tebaldi, Giuseppe di Stefano, Giuseppe di Luca, Riccardo Stracciari, Florence Austral, Kirsten Flagstad, Marjorie Lawrence, Frederich Schorr, Lauritz Melchior, Ludwig Suthaus, Ezio Pinza, Cesare Siepi, Georges Thill etc.... (I could name so many other singers....). Of course some singers of the past were sub-par, but the amount of fantastic singers was so much higher than it is today.
