自由诗(free verse)和散文诗(prose poem)是两个不同的诗歌类别，二者在形式上有一个最显著的不同点：自由诗分行，散文诗看起来像散文，而不是像自由诗那样分行。
According to Wikipedia,“a prose poem appears as prose, reads as poetry, yet lacks line breaks associated with poetry but uses…fragmentation, compression, repetition and rhyme and…poetry symbols, metaphor, and figures of speech. Prose poetry…is essentially a hybrid or fusion of [prose and poetry].”

Free verse closely follows the natural rhythms of speech, even though it's not always rhythmic.
Free verse is often described as following the natural rhythms of speech rather than the musical qualities of poetry. However, free verse can be rhythmic and melodic rather than sounding like natural speech, and it can contain rhymes and other patterns.
