Balduína "Bidu" de Oliveira Sayão (pronounced bee-DOO sigh-OWN) (May 11, 1902 – March 13, 1999) was a Brazilian opera soprano. One of Brazil's most famous musicians, Sayão was a leading artist of the Metropolitan Opera in New York City from 1937 to 1952.
Bidu Sayão was born to a cultured family in Botafogo, Rio de Janeiro. Her father died when she was five years old and her mother struggled to support her daughter's costly pursuit of a singing career. At just eighteen, the gifted Bidu Sayão made her major opera debut in Rio de Janeiro. Her acclaimed performance led to an opportunity to study with the famous Elena Teodorini, first in Brazil, then in Romania; and then to study with the renowned Polish tenor and tutor, Jean de Reszke, in Nice. During the mid-1920s and early 1930s, she performed in Rome, Buenos Aires, Paris, as well as in her native Brazil. While at the Teatro Costanzi in Rome, she met impresario Walter Mocchi (1870–1955). After his wife, soprano Emma Carelli, died in 1928, the two became romantically involved and were married. However, it did not last and in 1935 Sayão married Italian baritone Giuseppe Danise (1883–1963).
In 1930, she debuted at the Teatro alla Scala in Milan, and in the next year she sang a successful Juliette, in Gounod's Roméo et Juliette, at the Paris Opera. In the same year, she gained a great success with her debut at the Opéra Comique as Lakmé. She soon became one of the leading lyric coloratura sopranos in Europe, especially in Italy and France. Her repertoire included Lucia di Lammermoor, Amina in La sonnambula, Elvira in I puritani, Zerbinetta in Ariadne auf Naxos and Cecilia in Il Guarany, among other roles.
