in Brazil, and the first broadcast was the performance of the National Anthem with the new lyrics, followed by the speech by president Epitácio Pessoa, the first radio address by a Brazilian president. The national anthem is considered by the current Constitution of Brazil, adopted in 1988, to be one of the four national symbols of the country, along with the Flag, the Coat of Arms and the National Seal. The legal norms currently in force concerning the national anthem are contained in a statute passed in 1971 (Law No. 5,700 of 1 September 1971), regulating the national symbols. This law regulates in great detail the form of the national anthem and how and when it is to be played. The music of the national anthem was originally intended to be played by symphonic orchestras; for the playing of the anthem by bands, the march composed by Antão Fernandes is included in the instrumentation. This adaptation, long in use, was made official by the 1971 statute regulating national symbols. This same statute also confirmed as official the traditional vocal adaptation of the lyrics of the national anthem, in F major, composed by Alberto Nepomuceno. Due to the fact that the traditional vocal adaptation composed by Alberto Nepomuceno for Joaquim Osório Duque Estrada's lyrics of the national anthem was made official in 1971, other vocal arrangements (as well as other instrumental arrangements departing from the one recognized in law) are unofficial. Because of that, for the remainder of the Military Dictatorship era (that lasted until 1985), the playing of the anthem with any artistic arrangement that departed from the official orchestration and vocal adaptation was prohibited, and there was strict vigilance regarding the use of the National Symbols and the enforcement of this norm. Since the redemocratization of the country, far greater artistic liberty has been allowed regarding renderings of the national anthem. Singer Fafá de Belém's interpretation of the national anthem (initially criticized during the final days of the Military Dictatorship, but now widely accepted), is an example of that. In any event, although the use of different artistic arrangements for the anthem is now allowed (and although the statutory norms that prohibited such arrangements are no longer enforced, on the grounds of constitutional freedom of expression), a rendering of the national anthem is only considered fully official when the statutory norms regarding the vocal adaptation and orchestration are followed.
