What does the term "sempre" signify in a musical context?

In a musical context, the term "sempre" means "always." It is used to indicate that a particular directive or characteristic should be maintained consistently throughout the piece or a specific passage. For example, when a composer instructs to play "sempre legato," it means that the piece should be played in a smooth and connected manner at all times. This term emphasizes the continuity of the musical expression, urging the performer to uphold a certain quality throughout without deviation. Understanding this term helps in interpreting the composer's intent, ensuring that the performance aligns with the desired emotional and stylistic nuances. The other options do not convey the sense of continuity and consistency that "sempre" denotes, which solidifies why "always" is the correct interpretation in this context.
