Other forms: tetrameters
When a poem uses tetrameter, it includes lines of four metrical feet, or four stressed syllables. Many well-known poets and songwriters use tetrameter.
You may have heard the poem "Trees" by Joyce Kilmer — it's the one that goes "I think that I shall never see/A poem lovely as a tree." If that sounds familiar, then you already know what tetrameter sounds like. It's one of the most common ways to structure verse. From Emily Dickinson ("Because I could not stop for death/It kindly stopped for me") to the Beatles ("Picture yourself on a boat in a river"), you can find tetrameter almost anywhere!
