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.

– William Shakespeare

The Tempest, Act 1, Scene 2. Ariel sings a song to Ferdinand about his father Alonso and how death is part of the natural process. He uses an extended metaphor in commenting on Alonso’s death, or the appearance of it, as something positive in the cycle of life. Ferdinand thinks his father has drowned, but the audience already knows that he safely washed up on the island, so this is an example of the use of dramatic irony. Ferdinand is confused, as Ariel is invisible and he doesn’t know where the music is coming from. He is also sad, as the song convinces him that his father is indeed drowned.
