Demarczyk's repertoire consisted of demanding, not easily accessible interpretations of poems. Since her songs are often based on works by "classical" poets – both Polish such as Julian Tuwim and Krzysztof Kamil Baczyński and international like Goethe, Mandelstam, Rainer Maria Rilke, as well as avant-garde writers such as Miron Białoszewski – the genre that Demarczyk is associated with is called sung poetry.
