In Macbeth, please select examples from scene 4 of act 2 that illustrates the tone of the scene. What is the tone, and how does Shakespeare express it?

The tone of act 2, scene 4, is ominous as
people begin to question the "unnatural" events which are unfolding all around
them.

The old man who opens this scene declares that in 70 years, he has
never seen anything as disturbing as the events of 's murder. The skies are threatening, with
storms on the horizon. An unexplained darkness covers the earth even though it should be
daytime. A falcon, which often symbolizes victory, was seen attacked and killed in midair by an
owl, which often symbolizes magic or mystery. Thus, it seems that the world of the unknown is
overtaking their world of order.says that he witnessed Duncan's beautiful horses eating each
other. In short, their world is spinning out of control in the aftermath of Duncan's
death.

The men misplace the blame onto Duncan's sons because they have fled
in the aftermath of their father's murder; to Ross and , this makes them prime suspects. They
then declare thatwill most likely be the next king and hope that he will rule with as much
goodness as Duncan.

Of course, they are disillusioned about 's role in the
murder and do not see his ruthless quest to rule. The lies, unexplainable natural events, and
inability to see the truth build an ominous tone that further danger is on the
horizon.
