A quintilla is a Spanish stanza of five octosyllabic lines. The book comprises 46 poems, written in four-line stanzas (quatrains) of octosyllabic verse. In each stanza two rhymes alternate, in approximately octosyllabic lines. The Polo from Margarita is sung in octosyllabic or hendecasyllabic verses with varying rhyme schemes. The lyrics of plena songs are usually octosyllabic and assonant. The main theme is also based on an octosyllabic copla. The first was by Christopher Smart into octosyllabic couplets (London 1753). The octosyllable or octosyllabic verse is a line of verse with eight syllables. In the original French kyrielle, lines were generally octosyllabic. Chaucer used octosyllabic lines in "The House of Fame" but eschewed iambic rhythm. It is octosyllabic, like the Gayatri metre that is sacred to the Hindus.
