The aim of this article was the analysis of the meanings of song and their transformations in the poem by Cyprian Norwid “Do obywatela Johna Brown”. As a result of interpretational close-ups (especially to the initial phrase and the climax of this poem) the polysemic song by Norwid appears not only as a lyrical genre, a term synonymous to poetry in general but also as an act with performative and transgressive features leading the lyrical subject – also through a specifically ‘musical’ shaping of this poem – towards the experience of epiphany of sacrum (Marian and Christological motives).
