The song refers to the orixá Xangô. This deity is part of the African-rooted religions in Brazil, recognized as the orixá of lightning and thunder, of justice, characterized by strength and intolerance towards committed injustices. An artist with extensive experience in Afro-religious-Brazilian musicality, in "Canção pra Xangô," Libertu evokes the deepest elements of tradition. The artist rhythmically builds the song on the drum beats of Umbanda yards, especially on the "Barravento," "Cabula," and also "Maracatu" rhythms. The arrangements prioritize percussion elements, which lead the music through the sections. The harmony is provided by a guitar coupled with counterpoints performed by saxophone. In the recordings, Libertu played all the percussion instruments and the guitar. "Canção pra Xangô" can be categorized as a prayer-song and is part of the MPB tradition that recognizes, praises, and evokes the strength of ancestry.
