The statement " All poetry is rhyming verse," is false.
For instance, free verse poems will lack set meter, meaning the rhythm of the words, no rhyme scheme, or any particular structure. Free verse poems do not follow the rules, and have no rhyme or rhythm. In a poem, rhyme refers to the repetition of syllables, generally at the end of a verse line.
Rhyme words usually share all sounds following the word’s last stressed syllable.
