What does "legato" refer to in music?

In music, "legato" refers to a style of playing or singing where notes are connected smoothly and flowing, without any perceptible breaks between them. This technique creates a seamless and lyrical sound, contributing to the expressiveness of the music. The term translates from Italian to "tied together," reflecting the idea that each note is linked to the next, enhancing the melodic line's continuity.

Understanding "legato" is essential for interpreting musical scores correctly, as it indicates to performers how to articulate the notes for a specific emotional or stylistic effect. In contrast, the other terms mentioned pertain to different articulations or dynamics—such as light and quick movements, slower tempos, or variations in volume—that do not represent the smooth connection characterizing legato.
