The rondelet, not to be confused with the rondel or short rondel, is a seven-line French poem form that utilizes a refrain three times despite its brevity. As a result, the real challenge of the form is often seeing how much the poet can fit within the limited space left behind between the refrains.
The lai is a French form utilizing nine-line verses that are further divided up, structurally, into three-line units. Each verse has an AABAABAAB rhyme scheme, while each three-line unit has a 5-5-2 syllable structure. This makes for a poem form that is demanding, but aesthetically pleasing when properly achieved.
The dansa is a poem from the Old Occipital language, first introduced by the 13th century troubadours of southern France. It utilizes a quintain followed by multiple quatrains, repeating a refrain at the end of every verse. While originally lyric poetry, modern interpretations of the form often lack any definite meter.
