The song thất lục bát is a Vietnamese form, which consists of a quatrain comprising a couplet of two seven-syllable lines followed by a Lục bát couplet. Each line requires certain syllables to exhibit a "flat" or "sharp" pitch. Lines and stanzas are linked in a complex rhyme scheme. Examples in Vietnamese include: ⁕Chinh Phụ Ngâm by Ðoàn Thị Ðiểm ⁕Cung Oán Ngâm Khúc by Nguyễn Gia Thiều Although the Song Thất Lục Bát stanza is the most common way of incorporating the secondary song thất form into the primary lục bát form, two other methods have also been used: song thất couplets may be randomly interspersed within a long lục bát poem; and the two types may alternate in an odd number of couplets, in which case the series both begins and ends with a lục bát couplet.
