Temblor literally means "earthquake" or "tremor". It's a powerful word that creates a vivid image of shaking and instability.
In this song, Morat uses it as a metaphor for the intense emotional turmoil following a breakup. When he sings "Y ya pasó el temblor" (And the earthquake has passed), he's trying to convince himself that the chaotic, destructive phase of his heartbreak is finally over.
We have all told a tiny lie after a breakup just to save face, but in "Sin Ti", Morat and Jay Wheeler admit they built an entire script out of them. The singer confesses right out of the gate: "Decir que ya te olvidé es un mecanismo de defensa" ("Saying I already forgot you is a defense mechanism"). Instead of genuine healing, he survives by repeating rehearsed excuses whenever friends bring up his ex. He claims he deleted the photos, erased old texts, and keeps insisting "Borracho estoy mejor" ("I'm better off drunk") and "tú ya no eras para mí" ("you were no longer right for me"). It is a relatable, slightly embarrassing look at faking confidence until you trick your own brain.
The real punch in this track comes from the lyric "Se lo digo a otra gente pero sólo es para vendérmelo a mí" ("I say it to other people, but it's only to sell it to myself"). He even talks about an earthquake passing—"ya pasó el temblor" ("the tremor has already passed")—using the shock of natural disaster to describe the immediate chaos of a split. By repeating "Lo dije hasta que me convencí" ("I said it until I convinced myself"), he reveals the painful punchline: he only learned how to lie so well because it was the only way to make it through without her.
