"Of those who have been before her we were most frequently reminded of Madame Bishop's quality (not quantity) of voice. Their voices are of metal somewhat akin. Jenny Lind's had incomparably more power and more at all times in reserve; but it had a shade of that same veiled quality in its lowest tones, consistently with the same (but much more) ripeness and sweetness, and perfect freedom from the crudeness often called clearness, as they rise. There is the same kind of versatile and subtile talent, too, in Jenny Lind, as appeared later in the equal inspiration and perfection of her various characters and styles of song. Her's is a genuine soprano, reaching the extra high notes with that ease and certainty which make each highest one a triumph of expression purely, and not a physical marvel. The gradual growth and sostenuto of her tones; the light and shade, the rhythmic undulation and balance of her passages; the bird-like ecstacy of her trill; the faultless precision and fluency of her chromatic scales; above all, the sure reservation of such volume of voice as to crown each protracted climax with glory, not needing a new effort to raise force for the final blow; and indeed all the points one looks for in a mistress of the vocal art were eminently her's in Casta Diva. But the charm lay not in any POINT, but rather in the inspired vitality, the hearty, genuine outpouring of the whole--the real and yet truly ideal humanity of all her singing. That is what has won the world to Jenny Lind; it is that her whole soul and being goes out in her song, and that her voice becomes the impersonation of that song's soul if it have any, that is, if it BE a song. There is plainly no vanity in her, no mere aim to effect; it is all frank and real and harmoniously earnest. "She next bewitched all by the delicate naivete and sparkling espieglerie, interchanged with true love pathos, of her duet with Belletti, from Rossini's I Turchi in Italia, the music being in the same voice with that of his 'Barber of Seville.' The distinct rapidity, without hurry, of many passages, was remarkable in both performers. But perhaps the most wonderful exhibition of her vocal skill and pliancy and of her active intimacy with nature was in the Trio Concertante, with two flutes, from Meyerbeer's 'Camp of Silesia.' Exquisitely her voice played in echo between the tasteful flute-warblings of Messrs. Kyle and Siede. "But do not talk of her flute-like voice; the flute-tone is not one a real voice need cultivate; except where it silvers the edges of a dark mass of orchestral harmony, the flute's unmitigated sweetness must and should contrast with the more clarionet and reed-like quality of a voice as rich and human as that of Jenny Lind.
