http://buscon.rae.es/draeI/SrvltConsulta?TIPO...In the original lyrics, the author referred to a "guajira guantanamera" (a peasant girl from Guantánamo), but since the song itself is structured as a guajira (the Cuban rhythm, named after Cuban peasants), some people (erroneously) think that the chorus refers to the song itself (or, rather, its rhythmic structure), and not to an individual. In other words, the words are interpreted as an introduction to a "guajira, Guantánamo-style". This has essentially guaranteed that the chorus' lyrics still be used to this day, as evidenced by their use along with the (seemingly) unrelated Martí verses.
