What does a "movement" typically include in a symphony?

A movement in a symphony is defined as a complete and self-contained segment that can stand alone as a distinct part of the overall work. Typically, a symphony is structured in multiple movements, each varying in tempo, character, and sometimes key, contributing to a cohesive narrative or emotional journey throughout the performance.

Each movement often features its own themes and motifs, allowing composers to explore different ideas or emotions within the larger framework of the symphony. This segmentation is essential in classical music, as it not only creates variety but also allows performers to showcase different techniques and styles between movements.

In contrast, while dance sections might be present in some works, they do not universally define movements. Vocal parts are not typically a feature of symphonies, which primarily focus on instrumental music. A written score is indeed crucial for the performance of the symphony but does not define the concept of a movement itself.
