Crackle effect describes a textural quality in poetry where surface smoothness is disrupted by multiple small breaks, interruptions, or discontinuities that create an impression of fragmentation without complete disintegration. This technique involves introducing syntactic breaks, sonic disruptions, or semantic gaps that fracture the poem's surface unity while maintaining overall coherence. The crackle effect can suggest instability, energy, or the inadequacy of language to contain meaning, creating dynamic tensions between unity and fragmentation that engage readers in the active negotiation of textural complexity.

Crackle effect describes abrupt shifts in sound, syntax, or image that create textual friction—used to convey tension, fragmentation, or emotional volatility.
