Which term describes the performance style that avoids sounding lifeless in music?

Articulation is the term that describes the performance style in music that contributes to a piece sounding lively and expressive rather than lifeless. It refers to the way in which notes are played or sung, including the clarity and definition of each note's attack, duration, and release. Proper articulation can help convey the mood and nuances of the music, allowing performers to communicate their interpretation effectively.

For instance, using a combination of different articulations—such as staccato (short, detached notes) and legato (smooth, connected notes)—can enhance the expressiveness of a performance, making it feel more engaging. This contrasts with simply playing all notes uniformly, which can lead to a performance that feels flat and uninspired.

The other terms have distinct meanings that focus on different aspects of music. Legato pertains to the smooth connection between notes, staccato emphasizes a detached style, and dynamics refer to the varying levels of loudness and softness in music. While all these elements contribute to an overall performance, articulation specifically addresses the liveliness and expressiveness that keep music from sounding lifeless.
