What does "movement" refer to in the context of musical compositions?

In the context of musical compositions, "movement" refers to a complete, self-contained section within a larger musical work. This term is commonly used in classical music to denote distinct parts of a symphony, sonata, or concerto, among other forms. Each movement typically has its own thematic material, character, and often a different tempo or mood, contributing to the overall structure of the piece. For example, a symphony may consist of four movements, each with its own personality, yet all work together to form a cohesive whole.

Understanding this concept is essential as it deepens appreciation for how composers organize their ideas and how performers interpret these delineated sections. Movements allow for contrasts in dynamics, tempo, and emotional expression, providing listeners with a varied and rich musical experience.
