Words, phrases, or sounds repeated in immediate sequence, often line after line or stanza after stanza, creating rhythmic momentum and structural connection through cascading recurrence. Creates sense of continuous flow as each element links to what follows. Walt Whitman's long catalogues employ sequential echo with repeated constructions building cumulative power. Can involve exact repetition or systematic variation maintaining recognizable pattern. More sustained than isolated repetition, sequential echo creates architectural unity across extended passages while building toward climax through accumulation or developing theme through progressive variation.
