Ansani, or ANZANI, GIOVANNI, an Italian singer and composer, sang in London about the year 1781. Dr. Burney says his voice was one of the sweetest, yet most powerful ten-ors he ever heard. He was of an irritable disposition, and his wife, Signora Maecherini, a very indifferent singer, had a still worse temper. It is said that in Italy, when employed in the same theatre, if one happened to be applauded more than the other, they have been known to employ persons to hiss the successful rival.
