Es por ti

The song is a textbook example of early 2000s Latin pop-rock construction. It stays strictly within the diatonic scale of E major, avoiding secondary dominants or modal interchange. The emotional resonance is achieved through the contrast between the minor-heavy pre-chorus (vi-iii) and the bright, major-key chorus that prioritizes the IV chord to emphasize the 'opening' feeling of the hook.

Juanes wrote and performed this song as a slow-rock pop ballad. The lyrics center on the theme of love towards a romantic partner.

Released as the second single from the album Un Día Normal, this track became a cornerstone of modern Latin music by winning both Record and Song of the Year at the 2003 Latin Grammys. It reached number one in Mexico and maintains a legacy as one of the most recognized Spanish-language love songs of the 2000s.
