"Ariel's song" is a verse passage in Scene ii of Act I of William Shakespeare's The Tempest.
It consists of two stanzas to be delivered by the spirit Ariel, in the hearing of Ferdinand.
There is an extant musical setting of the second stanza by Shakespeare's contemporary Robert Johnson, which may have been used in the original production around 1611.
Through its use of rhyme, rhythm, assonance, and alliteration, the poem sounds like a spell.
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 changeInto something rich and strange.
