Here are some famous arias sung by leading ladies who have a mezzo-range (slightly lower than sopranos); the few contralto arias are usually in the roles of old ladies or witches, I am told.
MEZZO SOPRANO ARIAS:
1. BIZET: Carmen: L’amour est un oiseau rebelle (Habanera)
2. GOUNOD: Cinq-Mars: Nuit résplendissante
This is from a long forgotten political opera by Gounod,
4. MOZART: Don Giovanni: Vedrai, carino
5. MOZART: Cosi fan tutte: È amore un londrocello
6. DONIZETTI: La Favorite: O mon Fernand
7. HÄNDEL: Alcina: Mi lusinga il dolce affetto
8. MEYERBEER: Les Huguenots: Non, vous n’avez jamais, je gage
9. GLUCK: Orfeo ed Euridice: Che faro senza Euridice
10. MOZART: The Marriage of Figaro: Voi che sapete
