duple meter: Metrical patterns based on two-syllable feet such as iambs and trochees, creating binary rhythmic units alternating between unstressed and stressed syllables. Duple meter contrasts with triple meter (three-syllable feet) and provides the foundation for much English-language poetry. The two-beat pulse of duple meter feels natural to English speech patterns and walking rhythms, creating accessible, regular patterns. Understanding duple meter is fundamental to prosodic analysis and reveals how binary rhythmic organization shapes reader experience, creating expectations and emphases through alternating strong and weak positions.

Duple meter features two-syllable feet like iambs or trochees. This creates a binary, marching rhythm suitable for ballads, songs, and narrative verse, providing clear, simple rhythmic structure.
