Silva was working in a cabaret when she was discovered and offered a 10-year contract by
RCA. In the late 1930s, she met the
Puerto Rican composer
Rafael Hernández, who convinced her to join his Cuarteto Victoria. Myrta traveled with the group all over
Latin-America. Some time later, she also sang for another composer
Pedro Flores in his Sexteto Flores, where she was joined by
Daniel Santos and
Pedro Ortiz Dávila.
As a composer In 1941, aged 14, Silva composed her first song, "Cuando vuelvas" ("When You Return"), recorded by
Ruth Fernández. In 1942, she composed "En mi soledad" ("In My Solitude"), recorded by Daniel Santos, which became a hit in Latin America and in the Latin communities in the United States. Silva became the first woman certified as a
timbalera by the
American Federation of Music in 1943. In 1944, she wrote "Así es la vida" ("That's Life") and "Fácil de recordar" ("Easy to Remember") while she was performing in
Havana, Cuba. In 1956, Silva produced and transmitted from New York a television program,
Una hora contigo (
An Hour with You). The show was transmitted by Canal 4 in Puerto Rico and Myrta moved back to the island. In her show she re-created the innovative character of "Madame Chencha." "Madame Chencha" became the first
T.V. character dedicated to "rumors." This character created a lot of controversy between public figures and the television station, and as a consequence, Silva decided to leave the program and return to New York City.
In New York City In New York City, she composed "Puerto Rico del alma" ("Puerto Rico of my Soul"). Between 1962 and 1964, she composed the following hit songs: "Qué sabes tú" ("What Do You Know?"), "Tengo que acostumbrarme" ("I Have To Get Used To It"), "Juguetes del destino" ("Toys of Destiny"), and many others. Among her recordings are
Voces románticas de Puerto Rico (Romantic voices of Puerto Rico),
La Bombonera de San Juan (The Bombonera of San Juan) and
La compositora e intérprete (The Composer and Interpreter).
Una Hora Contigo (An Hour with You) During the mid 1960s, Silva hosted a weekly music variety TV show
Una hora contigo (
An Hour with You) on New York City's first Spanish language television station, WNJU-TV Channel 47. The program was hugely popular among the Latino audience, prompting the station to add an additional weekly program hosted by Silva titled
Tira y tápate. In the 1970s, Silva wrote "No te vayas de mi vida" ("Stay In My Life"), which was recorded and made popular by
Evelyn Souffront. In 1971, Silva returned to Puerto Rico with her television show
Una hora contigo, which this time was transmitted on Canal 11. This show was among the most popular programs in Puerto Rico. ==Later years==
