a villanelle is a poetic form nineteen lines long where the first and third lines rhyme, and then they're repeated throughout the poem with other lines that rhyme with them. The second line of the poem also rhymes with all the second lines of the other six stanzas. Probably the most famous villanelle is Dylan Thomas' Do Not Go Gentle into that Good Night.

a ghazal is a Persian poetic form ranging from approx. 5-12 couplets. The second line of each couplet either rhymes or repeats the same word as the previous second lines. In the last couplet, the poet often includes his or her own name.

a sonnet is a fixed poetic form, 14 lines long written in iambic pentameter. a Petrarchan sonnet is divided into an 8-line stanza, called an octave or octet, and a 6-line stanza, called a sestet. the rhyme scheme for the octet is set: abbaabba, and the rhyme scheme for the sestet may be either: cdecde or cdcdcd. there's usually a pivotal change of thought, tone or subject matter between the octet and the sestet. a Shakespearean sonnet, on the other hand, is divided into 3 four-line stanzas, called quatrains, and a 2-line stanza, called couplet, and its rhyme scheme is: abab cdcd efef gg. each stanza usually introduces a new idea, a slight shift in opinion, etc.

why i prefered to explain what those were is that i'd never heard of two of them before, so i imagined others might be intrigued as well. I was assigned to write one of my choice in a poetry writing class i'm taking

riddle: which one did I choose?
