What is the function of a glissando in music?

A glissando serves the function of enhancing expressiveness in music by providing a smooth, continuous connection between notes. This technique allows a performer to slide from one pitch to another, creating a fluid transition that can evoke a range of emotions and contribute to the overall character of a piece. The seamless movement can add nuance and depth to a melody, making it feel more dynamic and alive.

While rhythmic elements and dramatic pauses are vital components in music, they do not capture the specific role of glissando. Additionally, although glissando can sometimes signal a shift between musical ideas, its primary purpose is not to separate but to connect notes in a fluid manner. This unique quality of glissando sets it apart as a powerful expression tool in performance.
