Final answer:
Denzel's effective speech delivery included strong eye contact, proper posture, and the ability to vary tone and language to engage with the audience. His awareness of the rhetorical situation and use of rhetorical devices contributed significantly to the successful delivery of his audition story at the Broadway musical.
Step-by-step explanation:
The effectiveness of a speech largely depends on the speaker's ability to engage the audience through various rhetorical strategies and delivery techniques. Denzel's delivery, as described, capitalizes on strong eye contact, proper posture, intentional movement, and gestures to create a connection with the audience. These delivery elements are essential components of visual rhetoric, allowing the speaker to communicate effectively and establish trust with the audience.
Good speech delivery also includes the ability to vary the tone of voice according to the content, which Denzel achieved by being more compelling during the serious parts and relaxed during others. His use of language complemented this approach, aiming for clarity and understanding, which are indicative of a speech well-received by its audience. The evidence of descriptive detail, the effectiveness of dialogue, and action in speech, and the appropriate variation of sentence structures are all demonstrated in Denzel's narrative of his audition at the Broadway musical.
Moreover, the speaker's awareness of their rhetorical situation—including the narrator, message, audience, purpose, context, and culture—is crucial for the delivery to resonate with the audience. Through using rhetorical strategies such as parallelism and repetition, a speaker can enhance the speech's impact, as is reflected in Denzel's presentation.
