It was not until the late 1880s that she established herself in Italy, performing in Turin, Naples, and in Milan, where she appeared in December 1889 at La Scala as Eva in the Italian premiere of Wagner's Die Meistersinger von Nürnberg.

[2][3] In 1876, after appearing in Verdi's La traviata in Cremona, Gabbi joined an Italian opera company in Poland, performing in Warsaw, Kraków, and in Lemberg, where she was so successful that she was engaged for the next two seasons.

[2][3] From December 1880 to April 1881, she made guest appearances in two theatres in Havana, Cuba, in the title role of Donizetti's Lucrezia Borgia, gaining wide acclaim from both the critics and audiences.

On 6 December 1880, the Havana newspaper La Discusión commented on her performance, praising "her perfect intonation, the masterful projection of her voice, the exquisite color of her singing, her school, and above all her expressive feeling".

[3] She is remembered in particular for her success at the Teatro Colón in Buenos Aires and at the Don Pedro Theatre in Rio de Janeiro where she appeared in Aida, La traviata and Il Guarany.
