"Caña” is a flamenco “palo” which has been historically considered as the most important one. In "Escenas Andaluzas" of Estébanaez Calderón it was called "caña" to "the primitive core of Andalusian singing" and Garcia Matos, a professor, assured that “caña” came from a very old Andalusian singing. Some other authors discussed this musical etymology. For them, it is related to “soleá” or “toná”, the latter is difficult to prove.
"Caña” has undergone many changes in its history. Curro Dulce, Silverio and Antonio Chacon were the singers who achieved better the essence of this style.
Currently “caña” is a song which is not very celebrated because of its monotonous character with little emotional charge. Instead, ““seguiriya”” and “soleá” are preferred.
