A metaphor is an implied meaning or significance of a word or object that is different than the original meaning. In the play, Wilson uses many metaphors, the chief one being the search for one's song, or identity. Says Bynum to Herald: "Now, I can look at you, Mr. Loomis, and see you a man who done forgot his song. Forgot how to sing it. A fellow forget that and he forget who he is." Bynum does not mean that Herald has literally forgotten how to sing a song that he used to know. Instead, the song is a metaphor for Herald's identity, and the African-American cultural identity in general. Since this identity is derived from Herald's African past, in which music plays a large part, the metaphor becomes very fitting—and resonates with audience members if they are aware of this well-documented connection.
