A sea-change into something rich and strange

From The Tempest by William Shakespeare, Scene ii of Act I , Ariel's Song

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.
