The document discusses two forms of poetry: the sonnet and blank verse. A sonnet is a 14-line poem written in iambic pentameter with a rhyming couplet at the end. Blank verse is poetry written in iambic pentameter without rhyming, and can be of any length. It provides Elizabeth Barrett Browning's sonnet "How do I love thee?" as an example of a sonnet and Shakespeare's "To be or not to be" soliloquy from Hamlet as an example of blank verse.
