Final answer:
In poetry, the use of enjambed versus end-stopped lines can affect the poem's rhythm and emotional impact, while in music, the concept of beats is used by tuners to ensure instruments are properly tuned.
Step-by-step explanation:
The transition from enjambed lines to end-stopped lines in poetry can dramatically change the rhythm and flow of a poem, as indicated in the provided reference material. Piano tuners, conversely, rely on the phenomenon of beats to ensure instruments are properly tuned, listening carefully as the beat frequency decreases to zero when the struck tuning fork's frequency matches with the string's frequency being tuned. This method is not only applicable to pianos but also to instruments like twelve-string guitars and mandolins. Moreover, when reading poetry aloud, such as in Allen Ginsberg's "Howl," the length and structure of lines can affect how breath is used, highlighting feelings of frustration or desperation.
