In the third stanza of the poem, “O Captain my Captain!” the third line is an example of which element of sound?


Stanza 3

My Captain does not answer, his lips are pale and still;

My father does not feel my arm, he has no pulse nor will;

The ship is anchor'd safe and sound, its voyage closed and done;

From fearful trip, the victor ship, comes in with object won;

Exult, O shores, and ring, O bells!

But I, with mournful tread,

Walk the deck my Captain lies,

Fallen cold and dead.
