Answer:
You need to know the context of a people's music.
Explanation:
<u><em>One of the things that the 20th-century Anthropology brought was the concept of otherness</em></u>, or to be specific, the idea that the context which a certain civilization is based on it's important and must be considered. In this case where a piece of music is the study case, then the Anthropologist (or the specialist who is studying it)<u><em> should look at the people who created that song, analyzing their beliefs, social skills, cultural elements and points of view and, then, propose an understanding about that music.</em></u>
Agamemnon is furious with Calchas, saying that the seer enjoys delivering evil prophecies, but the king agrees to give up the girl. He insists, however, that one of the Achaeans give him a prize to compensate him for his loss.
Achilles is enraged by the request. The plunder has already been distributed, he argues, and a good man does not take back what he has given. Agamemnon and Achilles argue, each man insulting the other. Agamemnon threatens to take a prize if one is not given to him, and Achilles reminds him that all of the Achaeans are fighting against foes who have only wronged Menelaus. For the sake of the two royal brothers, the Argives bloody their hands against men who have done them no wrong. Achilles also complains that though he bears the heaviest burden in battle, it is the king who is always greedy for prizes. Achilles refuses to fight anymore: he will go home to Phthia. Agamemnon responds that to compensate for the loss of Chryseis, he will take Achilles' own prize, the girl Briseis. Depending on your point of view of the story, I could be one or the other, tis a matter of opinion
