Which term suggests playing a piece in a lively manner?

The term that suggests playing a piece in a lively manner is "lebhaft." This German word translates to "lively" or "brisk" in English and is commonly used in musical scores to indicate a spirited and energetic performance. It invites players to interpret the music with enthusiasm and vivacity, often leading to a faster tempo or a more animated style of playing.

In contrast, the other terms convey different meanings. "Frohlich" translates to "joyous" or "cheerful," which, while positive, does not directly imply the liveliness that "lebhaft" embodies. "Gesangvoll" means "singing" or "melodious," focusing more on the lyrical quality of the music rather than its liveliness. "Legerement," which can mean "lightly" or "easily," suggests a light touch but does not necessarily evoke the vigorous and spirited approach indicated by "lebhaft."
