The two kinds of parts with which she was especially identified—young mothers and women past their first youth—are still called "jeunes dugazons" and "mères dugazons" in French opera. Examples of the first are Jenny in La dame blanche and Berthe de Simiane in Les mousquetaires de la reine; of the second, Marguerite in Le Pré aux clercs. The type of voice for these roles is a light mezzo-soprano or a dark-colored soprano leggero, and they are generally less demanding technically.[citation needed]
