Free verse is a kind of poem with irregular syllables, rhythms and other forms of design. It pursues "organic form" and relies on the natural rhythm of speech. This kind of speech is "natural" to the theme and feelings of the poem. Free verse is not a modern invention, but with the arrival of modernism, it occupies an important position and constitutes a rebellion against the fixed form of19th century poetry. Free verse has no external form to use, and it may be the most difficult to write well compared with previous poems.
