The "Brazilian National Anthem" () was composed by Francisco Manuel da Silva in 1831 and had been given at least two sets of unofficial lyrics before a 1922 decree by president Epitácio Pessoa gave the anthem its definitive, official lyrics, by Joaquim Osório Duque-Estrada, after several changes were made to his proposal, written in 1909. The anthem's lyrics have been described as Parnassian in style and Romantic in content. History The melody of the Brazilian national anthem was composed by Francisco Manuel da Silva, and was presented to the public for the first time in April 1831. On 7 April 1831, the first Brazilian Emperor, Pedro I, abdicated the Crown and days later left for Europe, leaving behind the then-five-year-old Emperor Pedro II. From the Brazilian proclamation of independence in 1822 until the 1831 abdication, an anthem that had been composed by Pedro I himself, celebrating the country's independence (and that now continues to be an official patriotic song, the Independence Anthem), was used as the national anthem. In the immediate aftermath of the abdication of Pedro I, the anthem composed by him fell in popularity. Francisco Manuel da Silva then seized this opportunity to present his composition, and the anthem written by him was played in public for the first time on 13 April 1831. On that same day, the ship carrying the former Emperor left the port of Rio de Janeiro. The date of April 13 now appears in official calendars as the Day of the Brazilian National Anthem. As to the actual date of composition of the music presented in April 1831, there is controversy among historians. Some hold that Francisco Manuel da Silva composed the music in the last four months of 1822 to commemorate Brazil's independence (declared on 7 September 1822), others hold that the hymn was written in early 1823 and others consider the evidence of composition dating back to 1822 or 1823 unreliable, and hold that the Anthem presented on 13 April 1831 was written in 1831, and not before. In any event, the Anthem remained in obscurity until it was played in public on 13 April 1831. In style, the music resembles early Romantic Italian music such as that of Gioachino Rossini. Initially, the music composed by Francisco Manuel da Silva was given lyrics by Appeals Judge Ovídio Saraiva de Carvalho e Silva not as a national anthem, but as a hymn
