The novel 's title is taken from the popular Dominican merengue Mataron al chivo ( " They Killed the Goat " ) , which refer to Trujillo 's assassination on May 30 , 1961 . Merengue is a style of music created by Ñico Lora in the 1920s and actively promoted by Trujillo himself ; it is now considered the country 's national music . Cultural critics Julie Sellers and Stephen Ropp comment about this particular merengue that , by envisaging the dictator as an animal who could be turned into a stew ( as frequently happened with goats struck down on the Dominican Republic 's highways ) , the song " gave those performing , listening to and dancing to this merengue a sense of control over him and over themselves that they had not experienced for over three decades . " Vargas Llosa quote the lyrics to Mataron al chivo at the beginning of the novel .
