Corrido

The corrido (Spanish pronunciation: [koˈriðo]) is a famous narrative metrical tale and poetry that forms a ballad. The songs are often about oppression, history, daily life for criminals, the vaquero lifestyle, and other socially relevant topics. Corridos were widely popular during the Mexican Revolution and in the Southwestern American frontier as it was also a part of the development of Tejano and New Mexico music, which later influenced Western music.
The corrido derives mainly from the romance and, in its most known form, consists of a salutation from the singer, a prologue to the story, the story itself, and a moral and farewell from the singer. In Mexico, it is still a popular genre today.
Outside Mexico, corridos are popular in Chilean national celebrations of Fiestas Patrias.
