As with "I puritani", Callas learned and performed Cherubini's "Medea", Giordano's "Andrea Chénier" and Rossini's "Armida " on a few days' notice. Throughout her career, Callas displayed her vocal versatility in recitals that juxtaposed dramatic soprano arias alongside coloratura pieces, including in a 1952 RAI recital in which she opened with Lady Macbeth's "letter scene", followed by the "Mad Scene" from "Lucia di Lammermoor", then Abigaille's treacherous recitative and aria from "Nabucco", finishing with the "Bell Song" from "Lakmé" capped by a ringing high E "in alt" (E6).
