Iambic pentameter

Iambic pentameter is a type of rhythm or beat used in poetry. It's made up of 10 "beats" or syllables that are arranged in 5 pairs. Each pair consists of one unstressed syllable followed by one stressed syllable, like "da-DUM." When writing in iambic pentameter, the writer chooses words that fit this pattern of "da-DUM" to create a poem. The name "iambic pentameter" comes from two words: iambic, which means using the unstressed-stressed pattern, and pentameter, which means there are 10 beats. Iambic pentameter is a way to write poetry that sounds nice when it's read out loud.
