Caracoles
“Caracoles” is a flamenco style with origin in “cantiñas” dancing, more specifically in an "cantiña" called "La caracolera". It was developped at the end of the 19th century in Madrid. Singers used to add some lyrics and melodic verses to “caracoles” or simply merge it with other “cantinas”.
José de Sanlúcar is considered as first singer who magnified this singing, before Antonio Chacón spreaded it. Later, other singers such as El Niño de Almaden, kept this flamenco style. Currently this singing is rarely used.
