What does the word "sempre" signify when encountered in a musical context?

In a musical context, the term "sempre" is an Italian word that translates to "always." When it appears in scores, it typically serves to instruct the performer to maintain a consistent musical quality or characteristic throughout the piece or a specific passage. For example, if a composer writes "sempre legato," it directs the musician to play always in a smooth and connected manner without any sudden breaks in the sound. This consistent application of "sempre" adds to the expression and atmosphere of the music, emphasizing the importance of certain elements being sustained throughout the performance. Understanding this term helps musicians interpret and perform the music as intended by the composer.
