Pavor translates to "dread" or "terror". It's a strong and evocative word that conveys a deeper sense of fear than simply "miedo" (fear).
In the song, the artist sings, "Perderte sí me da pavor" (Losing you does give me dread). This emphasizes the intense fear and anxiety he feels at the thought of losing his beloved, making it a powerful and memorable expression of his emotions.
This is a song about falling for someone before you have any right to, and being frightened by how fast it happened. The singer admits he barely knows her and does not really have her yet, and that he is already afraid of losing her.
The chorus is his defence. He saw her coming and did not hesitate. He held her, kissed her, took the risk of telling the truth, opened his heart and gave his love with no conditions attached, all so that she would stay.
The second half is the waiting. He has done everything he could and now he counts the days to find out whether it was enough. If she decides not to come back, he says, love will stop making sense and he will want nothing to do with the world.
LA NUEVA ESCUELA take a well known romantic ballad, written by Leonel Garcia and first recorded by Sin Bandera, and rebuild it as plena, so a song about quiet dread turns into something a whole dance floor can sing back.
