Ms Caballé enrolled as a student at El Liceu Conservatory and took private lessons as well. After singing in Switzerland and Germany for some time, she returned to Barcelona, where she made her debut at El Liceu Opera House in 1962. A few important changes took place in her personal life too: Her brother Carles became her manager; also, she married Mr Bernabé Martí, a tenor himself.

In 1965 she took over Marilyn Horne´s commitment to sing Donizetti´s Lucrezia Borgia (Horne had fallen ill) at New York´s Carnegie Hall. The occasion was a great success and launched Ms Caballé´s international career. She travelled all over the world singing and recording operas and, following the evolution of her voice towards maturity, she was learning new roles all the time. She has performed about 100 of these (an incredibly huge repertoire for a singer!) She has had many glorious nights, for the benefit of music and her audiences. Most critics agree that her performances of Bellini´s Norma are just perfect.

But Ms Caballé is not easily satisfied, and she has devoted much time and energy to study rare operas (which had been more or less forgotten by producers, critics and audiences alike). The results have often been a hit. Surprisingly, Ms Caballé manages to find the time to sing with modern artists such as the unfortunate Freddie Mercury or the composer Vangelis.  No wonder Ms Caballé has won many important awards everywhere!
