The triplet poem is composed of a single verse in three lines. The rhyming schemes and syllable counts differ by the individual poems. As the poet, you have a tremendous amount of freedom with the triplet poem. A longer poem can be created by stringing together several individual triplet poems, either telling a story or exploring a theme.
Writing a Triplet Poem
Decide on the subject of your poem. This will help you determine your form.
Decide on the rhyming scheme you want to use. It is a common practice in triplet poems to have each of the three lines rhyme, or just the first and last lines.
Determine whether you want to have specific syllable counts for lines, such as 10, 12, 10 or 15, 12, 15.
Write the poem, based on the things you've decided.
