What is the term for the technique of playing notes in a smooth and connected manner?

The term for playing notes in a smooth and connected manner is "legato." This technique involves articulating notes in such a way that they are seamlessly connected, without any perceptible breaks in between them. Legato is often executed by smoothly transitioning from one note to the next, typically by using a gentle bow stroke on string instruments or by pressing keys in a way that maintains a flow of sound in keyboard instruments. This creates a lyrical and fluid sound that is characteristic of many melodic lines in music.

In contrast, other terms such as "staccato" refer to playing notes in a short, detached manner, where the notes are distinctly separated from one another. "Syncopation" involves emphasizing beats or parts of beats that are typically weak, contributing to a sense of rhythm that surprises or contrasts with the expected. "Marcatto," similarly, suggests playing notes with a strong emphasis but without the smooth connection that "legato" conveys. Thus, legato specifically highlights the smoothness and continuity in musical phrasing.
