Travesas comes from the verb atravesar, meaning "to cross" or "to traverse." While the more common form is atraviesas (from atravesar), the lyrics use travesas which is a less common, perhaps more poetic or regional, conjugation of a similar root.
In the song, it's used in the line "Para que la brisa travesas a tu cuerpo" (So that the breeze crosses your body). This evokes a beautiful, sensory image of the wind moving over one's skin, making it a unique and evocative choice for the lyrics.
Elsa y Elmar's "La Ventana" feels like a beautiful, introspective journey. The lyrics start with a curious question about a year, "el 66 año" [the year '66], and then move to the idea of returning home and a profile, "volver a casa y también un perfil" [return home and also a profile]. It makes you wonder if it's about looking back at the past or perhaps a specific memory.
The song then shifts to a more personal reflection, asking "qué te parece" [what do you think?] and "pero qué tal" [but how about that?]. It's as if the singer is in a conversation, searching for something or someone: "contigo si sigo buscando si me llega" [with you if I keep searching if it reaches me] or finding it alone, "sola si la tengo ya sí" [alone if I have it already, yes]. There's a lovely image of seeking, "y mira lo que buscamos" [and look what we're looking for], followed by a playful detail about accounts needing to be Italian, "explica que las cuentas deben ser italia" [explains that the accounts must be Italy]. The song ends with a sense of gratitude and wonder, inviting the breeze to cross your body "para que la brisa travesas a tu cuerpo" [so that the breeze crosses your body] for the first time on earth, and declaring "todo es para ti es para ti todo es para ti" [everything is for you, it's for you, everything is for you]. It's a sweet, almost meditative song about discovery and appreciation.
