The city of Huelva on the coast of Spain between Portugal and Cádiz is closely identified with the Fandangos. There are 32 types of Fandangos de Huelva, each associated with a different part of the city, the nearby mountains or coast, or with individual artists. The underlying form for all these Fandangos is the same, and the variations are in the melodies, lyrics, and the supporting harmony. The most frequently performed version of the Fandangos de Huelva is the Fandangos de Alosno, named for a village north of Huelva. The most common setting for Fandangos de Huelva is a group of friends gathered around a table after a meal or drinks. The guitarist provides constant accompaniment while individual singers provide letras or the group sings in chorus.

The dance is popular during the annual pilgrimage to Rocio – the Romería del Rocio.  Participants in this event dress in traditional costume and travel on foot, by car or in brightly decorated horse- or ox-drawn wagons.  All converge in the city of Rocio to participate in a weekend of religious ritual and fun. Today, the dances and songs are also popular in Spanish dance companies and in smaller flamenco performances, and are mostly accompanied by the guitar, cante, and castanets.The copla consists of five eight syllable lines. One line of the verse is usually repeated, making a six line verse. The underlying form of Fandangos de Huelva is the underlying form for all Fandangos Comarcales.
