Which of the following is an example of an action content in dance?

An example of action content in dance is traveling across the stage. Action content refers to the physical movements and activities that dancers perform, which can include traveling, turning, jumping, and any other bodily movements that create visual patterns and convey meaning in a dance performance. Traveling across the stage specifically highlights the movement aspect, as it involves physically moving from one location to another, which is a fundamental element of choreography.

The other options do not fit the definition of action content. Adjusting stage lighting is a technical aspect of production rather than a movement performed by dancers. The rhythm of the music pertains to the auditory elements that accompany a dance performance, rather than the physical actions of the dancer themselves. Practice sessions refer to the training and rehearsal time, which is part of the preparation for performance, but not an action performed during the dance itself.
