Cornisa literally means "ledge" or "cornice", referring to the decorative molding at the top of a building. It's a specific architectural term you don't often find in song lyrics.
In the song, Gustavo Cerati sings "Estamos al borde de la cornisa, casi a punto de caer" (We're on the edge of the ledge, almost about to fall). This creates a powerful, cinematic image of tension and anticipation, putting the characters in a risky, high-stakes situation that perfectly captures the thrill and suspense of the song's voyeuristic theme.
This song is all about watching someone from a distance. The singer takes on the role of a spy, saying, "Soy un espĂa, un espectador" (I am a spy, a spectator), as he watches someone through a Venetian blind, the "persiana americana" of the title. This isn't a creepy, one-sided thing, though. It's a game between two people who enjoy the tension.
The whole scene is built on anticipation. The singer prefers the person he's watching to be "inalcanzable" (unreachable) and "casi intocable" (almost untouchable). He knows the other person is enjoying the game too, singing, "Sé que te excita pensar hasta donde llegaré" (I know it excites you to think how far I'll go). It's about the thrill of the moment just before something happens, a feeling he calls "una condena agradable" (a pleasant sentence) and compares to being "al borde de la cornisa / Casi a punto de caer" (on the edge of the ledge / Almost about to fall).
Soda Stereo was a groundbreaking rock band from Buenos Aires, Argentina, formed in 1982 by Gustavo Cerati, Zeta Bosio, and Charly Alberti. They are celebrated as the best-selling Argentine band of all time, having sold over seven million records by 2007. Their music evolved from a new wave and ska-influenced sound in their early years to a more alternative rock style, highlighted by their iconic hit "De MĂşsica Ligera".
Throughout the 1980s and 1990s, Soda Stereo revolutionised Latin American rock with albums like Nada Personal, Signos, and CanciĂłn Animal. Known for their charismatic performances and innovative music videos, they left a lasting legacy in the Latin rock scene. After disbanding in 1997, the band reunited briefly in 2007 and again from 2020 to 2022, continuing to influence new generations of music lovers.
