National Symphony Orchestra (Dominican Republic)
The National Symphony Orchestra was officially created on August 5, 1941. Nevertheless, its history can be traced to the beginning of the 20th century, when under the initiative of Juan Bautista Alfonseca, the Octet of the Youth Casino was founded in Santo Domingo.
National Symphony Orchestra (Mexico)
On November 23, 1946, president Miguel Alemán proposed the creation of the National Institute of Fine Arts and Literature ("Instituto Nacional de Bellas Artes y Literatura"), known by the acronym INBA, and was formally opened on 1 January 1947, as a branch of the Secretaría de Educación Pública, (SEP) (Secretariat of Public Education). The first head of the INBA was Carlos Chávez, who created a new orchestra for the Conservatory (thus because the conservatory depended on the INBA administration). On January 19, 1949, Chávez resigned his job as conductor of the Symphony Orchestra of Mexico, to spend more of his time composing and directing the INBA, but the orchestra didn't disappear, because Chávez succeeded in making the government recognize a national ensemble (working on this issue, since he was appointed as head of the INBA), so the actual organization known as National Symphony Orchestra of México was established, and Eduardo Hernández Moncada was designated its first conductor in 1947, José Pablo Moncayo replaced him in 1949.
