The corrido () is a popular narrative metrical tale and poetry that forms a ballad. The songs are often about oppression, history, daily life for criminals, and other socially relevant topics. It is still a popular genre today in Mexico and even gained some popularity in the U.S. more specifically in California and Texas. Corridos were widely popular during the Mexican Revolutions of the 20th century. The "corrido" derives largely from the romance, and in its most known form consists of a salutation from the singer and prologue to the story, the story itself, and a moral and farewell from the singer.
