Intervallo literally translates to "interval" or "intermission". It's a word commonly used in Italian to refer to a break during a performance, like a movie or a play.
In this song, Emma uses it metaphorically to describe a pause or a temporary separation in a relationship. She sings, "Siamo solamente usciti all'intervallo" (We've only gone out for the intermission), suggesting that their story isn't over, but rather on a temporary break, creating a hopeful and intriguing image for the listener.
Emma's “Intervallo” turns a stalled relationship into a paused film. The hook keeps returning to one image — “Siamo solamente usciti all'intervallo” [We've simply stepped out for the intermission] — as if nothing has actually ended, only broken for a pause between scenes.
She insists the distance isn't really far: “Lì, proprio dietro l'angolo” [There, right around the corner]. The empty apartment still “Ha sempre il tuo odore” [always carries your scent], and she admits she can't close the gap on her own — “Mentre io sono qui neanche a metà strada” [while I'm not even halfway here]. It's less a breakup song than a refusal to call intermission the end.
