The song refers to the orixá Iemanjá. This deity is part of the African-rooted religions in Brazil, being a female orixá, recognized as the orixá of salt waters, patroness of fishermen, characterized by motherhood and issues related to the head and decisions of individuals. She is the most syncretized and worshipped deity in the African pantheon in Brazil, with her worship widespread from north to south, with many festivals and holidays in her honor in the country. An artist with extensive experience in Afro-religious-Brazilian musicality, in “Festa pra Iemanjá,” Libertu evokes the deepest elements of the tradition. The artist rhythmically constructs the song on the drum beats of Umbanda yards, especially on the "Ijexá," "Cabula," and also "Alujá" 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, flute, and a choir of female voices. In the recordings, Libertu played all the percussion instruments and the guitar. "Canção pra Iemanjá" can be categorized as a prayer-song and is part of the MPB tradition that recognizes, praises, and evokes the strength of ancestry.
