I had this question in school, it uses a onomatopoeia and an alliteration. The onomatopoeia is the words "Ding-Dong" because it imitates the sound of a bell and an onomatopoeia is where the word relates to a sound. The alliteration was the words are "Hark! Now I hear Them" and "Full Fathom Five thy Father Lies". Why? Well that is because an alliteration is where words with the same beginning sound occur or repeat after each other like , When We Were Washing dishes, We Wanted to Watch television about Whales after our chores. There you go! Hope it helps! :)
