Scalderà comes from the verb scaldare, meaning 'to warm' or 'to heat'. It's a beautiful and evocative word that goes beyond simple temperature.
In the song, the singer is leaving a lover to return to another. He asks, "Chi la scalderà ?" (Who will warm her?), implying not just physical warmth but also emotional comfort and affection. This makes it a poignant and memorable word in the context of the song's emotional dilemma.
This song tells a story from the perspective of a man who is leaving a woman after a one-night stand. He's a bit apologetic, saying "Mi dispiace di svegliarti" [I'm sorry to wake you] and admitting "Forse un uomo non sarò" [Perhaps I won't be a man], suggesting he feels a bit guilty or inadequate for his actions. He knows she won't forgive him, imagining her silently biting the sheets.
But here's the twist: he's not leaving because he's a jerk, but because his heart belongs to someone else. He keeps repeating, "Il mio posto è là " [My place is there] and "Nella mente c'è tanta tanta voglia di lei" [In my mind there's so much, so much longing for her]. He's worried about his true love waking up alone, asking "Chi la scalderà " [Who will warm her?]. It's a really interesting look at a fleeting encounter overshadowed by a deep, existing love.
