Cante jondo (Spanish: [ˈkante ˈxondo]) is a vocal style in flamenco, an unspoiled form of Andalusian folk music. The name means "deep song" in Spanish, with hondo ("deep") spelled with J (Spanish pronunciation: [x]) as a form of eye dialect, because traditional Andalusian pronunciation has retained an aspirated H lost in other forms of Spanish.
It is generally considered that the common traditional classification of flamenco music is divided into three groups of which the deepest, most serious forms are known as cante jondo.
