How does motivic fragmentation contribute to the overall structure and development of a musical composition?

Motivic fragmentation in music involves breaking down a musical idea into smaller parts and using them in different ways throughout a composition. This technique adds variety and interest to the music, creating a sense of continuity and development. By manipulating and reusing fragments of a motif, composers can create a cohesive structure and build tension and release, leading to a more dynamic and engaging musical experience.
