Sconsolato means 'inconsolable' or 'disconsolate'. It's a beautiful, expressive word that goes beyond just being 'sad' (triste), describing a profound sorrow that cannot be comforted.
In this powerful ballad, Andrea Bocelli sings "Sono triste e sconsolato" (I am sad and inconsolable). He uses this word to paint a picture of utter despair without his loved one, capturing the dramatic, heart-wrenching emotion that makes this song so moving.
This duet is about missing someone so much it feels like you can't function. The singers trade lines about how the more they think about their loved one, the more they miss them: "E più ti penso, e più mi manchi" (The more I think of you, the more I miss you). They're alone late at night, seeing the person they love with tired eyes and even hugging a pillow to pretend they're close.
The feeling of emptiness is extreme. The singers feel like "un pesce che / Non ha l'acqua per nuotare" (a fish that / has no water to swim in). They say the sun is gone and they feel like nothing without this person. The song ends on a very dramatic note: if they can't see their love again, they know what they'd do. They wouldn't just not live, they would die: "Morirei" (I would die).
