Cielito Lindo was written in 1882 by Mexican composer Quirino Mendoza y Cortés and became one of Mexico's most enduring folk songs. Its title means beautiful little sky, and the chorus urges the listener to sing and not cry because singing gladdens hearts. Performed for generations by mariachi bands and popular singers, it spread far beyond Mexico through films, recordings and sporting events, where crowds adopted it as an unofficial anthem. Online, the short chorus remains a shorthand for Mexican culture, celebration and collective singing.
