AGUJARI, LUCREZIA an Italian operatic singer, possessed of one of the most extraordinary voices, in re spect of its almost incredible compass, ever known. Mozart, who heard her at Parma in 177o, noted down some of the passages which she sang, showing her range to have extended from middle C to C in altissimo, or more than an octave above the B flat which is about the limit of the average soprano. At the same time she was a brilliant executant. Known (and advertised) as La Bastardella, on account of the circumstances of her birth, as the natural daughter of a man of rank, she paid many visits to London where she received as much as f I oo a night.
