She is most closely associated with roles such as Rossini's Rosina and La Cenerentola, and later Bizet's Carmen, admired for her technical virtuosity, musical intelligence, and beguiling stage presence. Berganza was a key singer in a Rossini renaissance which explored less performed operas and restored the leading roles to mezzo register.
