What does a slur over notes indicate?

A slur over notes indicates that they should be played smoothly and connected. This means that the notes should be executed in a legato manner, where there are no noticeable breaks or pauses between them. The slur instructs the performer to blend the notes together, creating a flowing and cohesive musical phrase.

By utilizing a slur, the performer achieves a softer and more lyrical sound, which is often desired in expressive passages of music. This technique contrasts with other articulation markings, such as staccato or accents, which indicate shorter or more emphasized notes. Understanding the function of a slur is essential for interpreting many musical styles and conveying the intended emotions in a performance.
