SparsI means "scattered" or "spread out". It's a wonderfully descriptive and poetic word that you won't hear every day.
In the song, Gino Paoli uses it to paint an intimate picture: "I tuoi capelli sparsi sul cuscino" (Your hair scattered on the pillow). This choice of word evokes a sense of peace, closeness, and tender romance, making a simple moment incredibly memorable.
If someone asked you what you would do with just sixty minutes left, Gino Paoli has an absurdly romantic answer ready. In Vivere Ancora, he bargains for a tiny sliver of time: Vivere ancora soltanto per un'ora (To live on for just one hour). He does not ask for money, fame, or a miraculous cure. He simply wants to hold his partner in his arms, erase every lingering worry from her face, and make sure she knows that his life belongs entirely to her now.
The song turns nocturnal and intensely physical as the clock ticks down. Paoli trades the daytime world for a quiet sanctuary: Poter sentire vicino alla mia mano / I tuoi capelli sparsi sul cuscino (To be able to feel close to my hand / your hair scattered on the pillow). It is a classic Italian pop ballad setup, completely stripped of distractions. He waits for the sunrise through the window with their eyes locked (con gli occhi dentro agli occhi), finally repeating that his fate has blended permanently into hers: È diventato tuo (It has become yours). It is dramatic and desperately tender, built on the fantasy that one single hour of total closeness can outlast anything.
