Copla.

A verse form of Hispanic origin, usually sung, consisting of four eight-, six- or five-syllable lines generally rhymed ABCB. Often improvised, coplas relate humorous incidents, amorous sentiments, current or historical events or merely comment on daily life or the natural environment of the singer. Witty use of slang expressions and double meanings add to their often erotic nature. Coplas are commonly used in the rajaleņas, torbellinos and guabinas of Colombia, in the corrido of Mexico, and in the villancicos, saetas, vidalas, chacareras and vidalitas of Argentina.
