Final answer:
Rising intonation is used in open-ended questions and indicates shifts in a poem's mode or voice, while falling intonation is typical in declarative statements, commands, and yes/no questions, and is also found in trochaic rhythm.
Step-by-step explanation:
In English, a rising intonation phrase is typically observed at the end of a question that is open-ended, such as when the answer is not a simple yes or no. For example, 'What are you doing this weekend?' uses rising intonation. On the other hand, a falling intonation phrase is often found at the end of declarative statements, commands, or when a question expects a yes or no answer. An example of falling intonation would be the statement 'I'm going to the store.'
Intonation can also indicate shifts in a poem's mode or voice, or be used to highlight a list of actions.
In poetry, rhythm is described in terms of patterns of stressed sounds, like the rise and fall in iambic or trochaic feet. For instance, the iamb has a 'rising' rhythm, exemplified in words like 'destroy,' while the trochee has a 'falling' rhythm, as found in words like 'lovely.'
