Dactylic meter is a rhythmic pattern commonly used in poetry, characterized by a specific arrangement of syllables. It consists of a long syllable followed by two short syllables, creating a "da-DUM-da" sound. This meter is often found in classical poetry and can evoke a lively or dramatic tone. One of the most famous examples of dactylic meter is found in Henry Wadsworth Longfellow's poem "Evangeline." The use of this meter can enhance the musicality of a poem, making it more engaging for readers and listeners alike.
