We have been spell-bound by the ravishing tones of Patti, Sontag, Malibran, and Grisi; we have heard the wondrous warblings of “the Nightingale;” and we have listened with delight to the sweet melodies of the fair daughter of Erin; but we hesitate not to assert that, with one year’s tuition from the world-famed Emanuel Garcia, Miss Greenfield would not only compare favourably with any of the distinguished artists above named, but incomparably excel them all.

We hoped, ere this, to hear of Miss Greenfield proceeding to England. Queen Victoria is a thorough judge of music, and a kind and generous patron to musicians,—Miss Greenfield’s complexion would not bar her entrance to Buckingham Palace, nor would it shock the nerves of the most delicate lady of the court there. The Black Swan should sail to Europe.

The Globe, Toronto, May 12-15th, 1852.

Any one who went to the concert of Miss Greenfield on Thursday last, expecting to find that he had been deceived by the puffs of the American newspapers, must have found himself most agreeably disappointed.

Mr. Becht, the pianist of the party, commenced the evening with a very brilliant performance, which showed that his talents, if not of the very first rank, nearly approached to that point. He has a very considerable share of taste, but his forte passages were the finest, and were warmly applauded. After he had retired there was a general hush of expectation to see the entrance of the vocalist of the evening, and presently there appeared a lady of a decidedly dark colour, rather inclined to an embonpoint, and with African formation of face. She advanced calmly to the front of the platform, and curtised very gracefully to the audience. There was a moment of pause, and the assembly anxiously listened for the first notes. They were quite sufficient. The amazing power of the voice, the flexibility and the ease of execution took the hearers by surprise, and the singer was hardly allowed to finish the verse ere she was greeted with the most enthusiastic plaudits, which continued for some time. The higher passages of the air were given with clearness and fulness, indicating a soprano voice of great power. The song was encored, and Miss Greenfield came back, took her seat at the piano, and began, to the astonishment of the audience, a different air in a deep and very clear bass or barytone voice, which she maintained throughout, without any very great appearance of effort or without any breaking! She can, in fact, go as low as Lablache, and as high as Jenny Lind, a power of voice perfectly astonishing. It is said she can strike thirty-one full clear notes, and we could readily believe it. After the surprise had subsided, there was time to find out the errors and defects. It must be confessed that Miss Greenfield has a very heedless way of throwing her beautiful notes about, has far from perfect command over them, and wants the knowledge of ornamental points, which can only be given by instruction from the best masters. There were plenty evidences that it was not from lack of ability to understand what was required, that these defects existed. The introduction of the deeper voice in the treble songs was a singularity, but was also an unpleasing offence against the ear.

Miss Greenfield is said to have great facility in acquiring the knowledge of music, and will certainly under proper tuition become distinguished.

The company to-night perform in Hamilton. We hope on their return we may have another opportunity of listening to Miss Greenfield’s wonderful strains, and Messrs. Becht and Schmittroth’s excellent instrumentalization.

Auburn, New York, May 21st, 1852.

This evening the citizens of Auburn are to have the pleasure of witnessing the vocal powers of the Black Swan. It is not a year since this candidate for public patronage made her appearance in the concert room, but yet she has won a reputation that everywhere secures her crowded houses. Her recent tour in the western States was eminently successful, and her concerts were referred to in the papers, as being equal in interest to those given by the most celebrated vocalists of the day. The entertainment this evening will be given at Markham Hall.
