Sestain

A sestain is a six-line poem or repetitive unit of a poem of this format (musaddas), comparable to quatrain (Ruba'i in Persian and Arabic) which is a four-line poem or a unit of a poem. There are many types of sestain with different rhyme schemes, for example AABBCC, ABABCC, AABCCB or AAABAB. The sestain is probably next in popularity to the quatrain in European literature. Usually there are three rhymes in the six-line strophe, but sometimes there are only two.
