Carl Van Vechten,
The Merry-Go-Round
“ One touch of drama or emotion and their voices disappear. Remember Nellie Melba's sad experience with Siegfried. The great Mario had scarcely studied singing (one authority says that he had taken a few lessons of Meyerbeer!) when he made his début in Robert, le Diable and there is no evidence that he studied very much afterwards. Melba, herself, spent less than a year with Mme. Marchesi in preparation for her opera career. Mme. Galli-Curci asserts that she has had very little to do with professors and I do not think Mme. Tetrazzini passed her youth in mastering vocalizzi. ”
