Radif is a traditional form of Persian poetry that consists of a repeated refrain or phrase at the end of each couplet. This structure enhances the musicality and emotional impact of the poem, allowing poets to express complex themes and feelings. The Radif is often paired with a ghazal, a popular poetic form in Persian literature. In Radif, the repeated phrase can vary in length and is usually accompanied by a specific rhyme scheme. This technique has been used by many renowned Persian poets, such as Hafez and Rumi, to create memorable and resonant works that continue to be celebrated in Persian culture today.
