Tabú translates to 'taboo', something that is forbidden or restricted by social custom. It's a fascinating word choice because it's a cognate, making it easy for English speakers to recognize.
What makes it unique in this song is the line "Me invento un nuevo tabú" (I invent a new taboo for myself). The singer is creating his own forbidden subject, likely the memory of a past love, as a way to cope with the pain. This powerful concept drives the emotional heart of the song.
Tabú is a bilingual whirlwind of emotion where Pablo Alborán and Ava Max play two lovers who feel time slipping through their fingers. The ticking clock (tic tock… tic tac) and space-filled images of stars and moons create a sense of urgent, almost cosmic heartbreak. Both voices beg the other not to let their passion become a taboo topic while admitting how impossible it feels to erase the marks they have left on each other’s hearts.
Despite their pain, hope glows in every line. They recall the magical early days “when only your eyes could see mine” and promise that only by standing together can they “break the taboo,” reigniting the fire they once shared. It is a dramatic duet about refusing to surrender to silence, fighting against distance, and believing that love strong enough to cross languages can also cross darkness and time.
