Anonymous, The Black Swan at Home and Abroad
“ The musical powers of Miss Greenfield are said to be of the most wonderful character. The Press in every place where she has appeared, in concert, are united in singing her praises. Those who have heard her, assure us that the compass of her voice is truly remarkable. It is said to embrace twenty-seven notes, reaching from the sonorous bass of a barytone, to a few notes above even the highest of Jenny Lind’s. With such powers, and with enthusiasm and perseverance corresponding to them, she is destined to take the highest rank in the divine science to which she has devoted herself. ”
