Which of these lines from full fathom five makes us of alliteration

"Full Fathom Five" by - William Shakespeare 

Full fathom five thy father lies; 
Of his bones are coral made; 
Those are pearls that were his eyes; 
Nothing of him that doth fade 
But doth suffer a sea change 
Into something rich and strange. 
Sea nymphs hourly ring his knell; 
Ding-dong. 
Hark! Now I hear them–Ding-dong bell.
