The problems discussed in the article pertain to music-literary relationship. The arts dialogue is approached here as based on the interpretation of Stanislaw Baranczak's poem From the window on some floor this Mozart's aria. The reading of the poem is subject to music reception style, thus musical expectations from a literary text which induces the reader to make musical retorts - musical unequivocals. Mistrust of meanings closed in words leads to anagrams (F. de Saussure's theory) and to the search of order set by the classical harmony. The intertextual parallel drawn between the poem and the lyrics of Non so piu from Mozart's The Wedding of Figaro shows interdisciplinary solutions to be found at the crossroad of the poem, music, Italian aria's text and its Polish translation by Baranczak.
