A villancico is a traditional Spanish song that originated in the late Middle Ages. Initially, these songs were secular and often featured themes of love and nature. Over time, they evolved to include religious content, especially during the Christmas season, becoming popular in both folk and liturgical contexts. Typically, villancicos are characterized by their simple melodies and repetitive structures, making them easy to sing. They often incorporate elements of Spanish folklore and are performed in various settings, from church services to festive gatherings, reflecting the rich cultural heritage of Spain and Latin America.
