Question

The slit drum began its life in Central Africa, in the region where Sudan and the Congo share a frontier, and it would have been part of the court orchestra of a powerful chief... The flanks of the drum have been carved to different thicknesses, so that a skilled drummer with a traditional drumstick can produce at least two tones and as many as four distinct pitches.

How would adding an audio version of what a slit drum sounds like enhance the listener's experience of this part of the text?

It would signal to the listener that more important ideas about the slit drum’s history would be coming in the next section.
It would emphasize to the listener how different drums and other musical instruments sounded like in the past.
It would make the listener more able to feel the same emotions as the people who had heard the drums in the past.
It would make it easier for the listener to duplicate the sounds the drums made on his or her own musical instruments.

Answer 1

"It would make the listener more able to feel the same emotions as the people who had heard the drums in the past."

Reason: hearing the actual sound recreates part of the original sensory context, making the description more vivid and helping listeners empathize with historical listeners — more so than just signaling upcoming ideas or enabling technical replication.
