Answer:
The sound device shows how helpless love is in relation to time. As time passes, love declines.
Step-by-step explanation:
The poem talks about the changes that love goes through over the years and how the love of many is diminished and ended over time. Lines 24-26 report this with greater emphasis, through the use of rhymes that impose a musicality and a feeling that time is moving rhythmically. This shows the pressure of time on love, as it reinforces the idea that love can decline if it is not used soon.
