How many characters are singing in the excerpt?

The correct answer indicates that three characters are singing in the excerpt. This can be identified by the distinct vocal lines or harmonies that each character contributes to the piece. Listening closely, you can distinguish different singing styles, tonal qualities, or lyrical content that suggest more than one voice is present.

It's common in musical excerpts for multiple characters to interact through singing, often to convey dialogue, emotion, or to enhance the storytelling aspect of the piece. The complexity of the arrangement can provide clues about the number of singers, such as overlapping phrases or layered harmonies that signal additional voices participating in the performance.

In this case, since there are interpretations or distinct individual contributions from three unique characters, it reinforces the conclusion that the correct choice is that three characters are indeed singing.
