“Debla” ("goddess" in the language of Spanish gypsy) is a flamenco “palo” derived from “toná”. It was a relatively popular singing in the mid-nineteenth century.
“Debla” was driven by singers such as Varea el Viejo, El Fillo and El Planeta. It is similar to “carcelera” and “martinet”. “Debla” is, in fact, very similar to this latter. They are almost equal in their poetic structure and musical concept but it has a larger structure recharged of "melismas" and more sorrowful and devastated. It is composed by a four verse stanza and belongs to singings without guitar accompaniment.
For being a singing full of melismatic decoration, it requires a singer with favorable skills to performance it, because it's difficult to sing it.
