Tonás is a “palo”, a flamenco subgenre. It belongs to the wider category of Cantes a palo seco, palos that are sung a cappella. Owing to this feature, they are considered by traditional flamencology to be the oldest surviving musical form of flamenco. The first known flamenco singer, Tío Luis el de la Juliana, who lived in Jerez de la Frontera in the last third of the 18th century, was said to have excelled in this palo.
