It is this element of accident and uncertainty that lowers the value of many German singers. Herr Niemann, for instance, has moments--and, indeed, whole evenings--when his voice, seemingly rejuvenated, not only rises to sublime heights of dramatic passion, but possesses rare sensuous beauty; while on other occasions the sound of his voice is almost unbearable. Niemann, of course, is fifty-eight years old, but many of the younger German singers too often have their bad quarter-hours; and even Lilli Lehmann--whom I would rather hear for my own pleasure than any other singer now on the stage--emits occasionally a disagreeable guttural sound. Nothing of the sort in Mme. Patti, whom Niemann no doubt is right in pronouncing the most perfect vocalist, not only of this period, but of all times. I, for my part, have never cared much for the _bel canto_ as such, because it is so often wasted on trashy compositions. Yet, when I heard Mme. Patti for the first time in New York, I could not help indulging in the following rhapsody: "The ordinary epithets applicable to a voice, such as sweet, sympathetic, flexible, expressive, sound almost too commonplace to be applied to Patti's voice at its best, as it was when she sang the _valse_ Ombra Leggiera from 'Dinora,' and 'Home, Sweet Home.' Her voice has a natural sensuous charm like a Cremona violin, which it is a pleasure to listen to, irrespective of what she happens to be singing. It is a pleasure, too, to hear under what perfect control she has it; how, without changing the quality of the sound, she passes from a high to a low note, from piano to forte, gradually or suddenly, and all without the least sense of effort. Indeed her notes are as spontaneous and natural as those of a nightingale; and this, combined with their natural sweetness and purity, constitutes their great charm." A few months later, when Patti gave one of her innumerable farewell performances, I was again forced to admit that she is the greatest of living lyric sopranos, but took the liberty to express my conviction that "the charm of her voice is almost as purely sensuous as the beauty of a dewdrop or a diamond reflecting the prismatic colors of sunlight."
