Tyger burning bright, In the forests of the night: What immortal hand or eye, Dare frame thy fearful symmetry The ballad stanza consists of the iambic tetrameter with a rhyme scheme of ABCB (see ballad stanza for more details). An example can be found in “La Belle Dame sans Merci” by John Keats. I saw pale kings and princes too, Pale warriors, death-pale were they all; They cried—‘La Belle Dame sans Merci Thee hath in thrall!’ The Ruba'i form of rhymed quatrain was favored by Persian-language poet Omar Khayyám, among others. This work was a major inspiration for Edward FitzGerald's Rubaiyat of Omar Khayyam. The ruba'i was a particularly widespread verse form: the form rubaiyat reflects the plural. One of FitzGerald's verses may serve to illustrate: Come, fill the Cup, and in the fire of Spring Your Winter garment of Repentance fling: The Bird of Time has but a little way To flutter—and the Bird is on the Wing. The Midnight Songs poetry form is from Fourth Century China, consisting of regular five-character lines, with each quatrain formed from a pair of rhymed couplets. The person matter involves the personal thoughts and feelings of a courtesan during the four seasons, into which the quatrains are individually assigned. Shairi (also known as Rustavelian Quatrain) is an AAAA rhyming form used mainly in The Knight in the Panther's Skin. The Shichigon-zekku form used on Classical Chinese poetry and Japanese poetry. This type of quatrain uses a seven characters length of line. Both rhyme and rhythm are key elements, although the former is not restricted to falling at the end of the phrase.
