A formal approach to organizing closing echoes according to specific structural patterns such as refrain schemes, repeated end-words, or systematic sonic correspondences. More architecturally deliberate than casual repetition, these patterns create predictable yet satisfying returns of familiar elements. Sestinas demonstrate elaborate closing echo patterns through their envoi recycling all six repeated end-words in condensed form. Villanelles use tightly structured closing echo patterns with alternating refrains. Such patterns provide both constraint and opportunity, challenging poets to achieve variation within repetition while maintaining structural integrity.
