The proposal of this article is to present an interpretative reading of lyrics of the song “Angélicaâ€, of Chico Buarque, rescuing on scheme enunciation-enunciation, the linguistics traits that point out the enunciator subjects on a discursive production of the song. In that poem, we believe that when it is constituted, the subjected of enunciation establishes with its interlocutor and the referent directing the sense for a denounces against the silence required in the historical context of the dictatorship, building on poetic enunciation of the song a historical document of a time. We support our interpretative analysis based on the works of Bakhtin (1999), Benveniste (1989-1995), inter alia, contributing somehow, for the rescue of linguistics strategies that direct the meaning of the song for a historical and social dimension.
