* Free verse is poetry that doesn't follow a strict rhyme scheme or meter. It is characterized by its flexibility and freedom of form.
* Blank verse is a specific type of free verse that uses unrhymed iambic pentameter (five pairs of unstressed and stressed syllables per line).
While "free verse" is the broader term, it's important to note that "blank verse" is often used to describe a specific type of free verse with a distinct rhythm.
