The Sierra Morena is one of the main systems of mountain ranges in Spain. It stretches for 450 kilometres from east to west across the south of the Iberian Peninsula, forming the southern border of the Meseta Central plateau and providing the watershed between the valleys of the Guadiana to the north and the west, and the Guadalquivir to the south.

"Cielito Lindo" is a Mexican folk song or copla popularized in 1882 by Mexican author Quirino Mendoza y Cortés. It is roughly translated as "Lovely Sweet One". Although the word cielo means "sky" or "heaven", it is also a term of endearment comparable to "sweetheart" or "honey". Cielito, the diminutive, can be translated as "sweetie"; lindo means "cute", "lovely" or "pretty". The song is commonly known by words from the refrain, "Canta y no llores", or simply as the "Ay, Ay, Ay, Ay song".
