Which of the following would be most appropriate for introducing a speech about alternative music?

Playing a brief excerpt from a song is particularly effective for introducing a speech about alternative music because it engages the audience's auditory senses and provides a direct experience of the genre being discussed. This method not only captures attention but also sets the tone for the speech by showcasing the sound and style of alternative music. It allows the audience to grasp the essence of the genre immediately, creating a connection to the content that will follow.

Additionally, using an excerpt can evoke emotions and memories associated with the music, enhancing the audience's interest and involvement in the topic. It's a dynamic way to establish relevance and context, making the introduction memorable and impactful. Engaging the audience in this way can effectively lay the groundwork for further discussion about the themes, artists, or cultural significance of alternative music in the speech.
