Opera Singer. A mezzo-soprano of wide repertoire, she shall be remembered both for the Bel Canto roles of Rossini, Donizetti, and Bellini, and for the heavier fare of Giuseppe Verdi and other later composers. Raised at her mother's ancestral home in Sardinia, she was schooled at a convent in Rovigo, made her professional debut at Montagnana in 1928, and first gained notice for singing the prostitute Maddalena from Verdi's "Rigoletto" and similar comprimario roles. After further voice training and winning a 1933 Bel Canto competition in Florence she joined La Scala Milano on February 6, 1936, bowing as a Flowermaiden in Wagner's "Parsifal" and was to remain with the company until her 1966 retirement, gradually taking on more significant parts including the title role of Rossini's "La Cenerentola", Rosina in the same composer's "The Barber of Seville", Charlotte from Jules Massenet's "Werther", Santuzza in Mascagni's "Calalleria Rusticana", Octavian in Richard Strauss' "Der Rosenkavalier", and the title 'heroines' of Bizet's "Carmen", which she sang about 200 times, and Saint-Saens' "Samson et Dalila". She was also well noted as several of Verdi's lead mezzos including Amneris in "Aida", Azucena of "Il Trovatore" and Princess Eboli from "Don Carlo". Establishing herself as a major star with the title lead in Ambroise Thomas' "Mignon" in 1947, Giulietta soon saw other other significant debuts including the Edinburgh Festival in 1947 as Cherubino in Mozart's "The Marriage of Figaro", London's Covent Garden in 1953, San Francisco as Charlotte also in 1953, and in 1954 the Lyric Opera of Chicago where she bowed as Adalgisa in Vincenzo Bellini's "Norma" opposite Maria Callas. She sang the first of her 28 performances at New York's Metropolitan Opera on opening night of the 1959 season receiving good reviews as Azucena in an "Il Trovatore" cast that included tenor Carlo Bergonzi and the legendary baritone Leonard Warren. After leaving the stage on February 6, 1966, as Servilla from Mozart's "La Clemenza di Tito", a role she learned in two days so she could retire on the 30th anniversary of her debut, Gulietta taught and worked as a director, participating in the documentary films "Tosca's Kiss" (1984) and the 1999 "Opera Fanatic". At her death from advanced age a significant portion of her large recorded legacy was available on CD.
