The Brazilian National Anthem (Hino Nacional Brasileiro in Portuguese) was first composed by Francisco Manoel da Silva upon independence from Portugal in 1822, but was not used until 1890. Instead, the first anthem was the Hino da Independência composed by the first emperor, Pedro I.
With the establishment of a republic in 1889, lyrics were written by Joaquim Osório Duque Estrada to go with Francisco Manoel da Silva's song. However, as the lyrics did not fit well with the original music, changes had to be made to it.
When played in its purely instrumental form the original music is used and the anthem is a lot shorter. The unisong-song version (which is the official one) plays a modified version of the music twice (because the lyrics are too extense).— Excerpted from Brazilian National Anthem on Wikipedia, the free encyclopedia.
