What is the sequence of stressed and unstressed syllables?

A sequence of stressed and unstressed syllables is the pattern of accents in a line of poetry or verse, known as its meter. For example, in iambic pentameter, the most common meter in English poetry, there are five feet per line with each foot consisting of an unstressed syllable followed by a stressed syllable. This creates a pattern of da-DUM da-DUM da-DUM da-DUM da-DUM.
