What does "sempre" suggest when used in musical notation?

The term "sempre" in musical notation suggests that the performer should "always" maintain the indicated style or character throughout the piece. This directive is about consistency; it instructs musicians to adhere to the specified dynamics, articulation, or other expressive markings continuously. For example, if a passage is marked "forte sempre," it means to play strongly at all times in that section, ensuring the same intensity is preserved throughout. Understanding this term is essential for musicians, as it influences how the music is interpreted and performed, maintaining a cohesive sound and emotional expression across the performance.
