The strange gift of the negro in music has been the subject of remark for years. But it has been only recently that the negro has received any scientific training in voice culture. βThe Black Patti,β who will give one iarewell concert at Music Hall Thursday night, is a brilliant example of what thorough training will do to a remarkable natural voice. This brilliant prima donna burst upon New York, at Madison Square Garden, singing to 15,000 people, and produced a genuine sensation. She became at once the theme of laudation by the press and the talk of society. Since then Mme. Jones has given more than a hundred concerts in New York and always to crowded houses. 8he is one of the most popular concert singers before the public today. She will leave for Europe in September, under the management of Colonel Mapleson, and will be gone five years.
