Hamlet fits within Anoulih's discussion of tragedy. In this play most of the characters die. It is expect that death will befall them. Since the play's beginning, the foundation for tragedy is set. We learn that Hamlet is in mourning. The King is trying to convince him to show sorrow. It is unmanly. Hence, a foundation for irony is set up. Tis sweet and commendable in your nature, Hamlet,

To give these mourning duties to your father:

But, you must know, your father lost a father;

That father lost, lost his, and the survivor bound

In filial obligation for some term

To do obsequious sorrow: but to persever

In obstinate condolement is a course

Of impious stubbornness; 'tis unmanly grief; (Shakespear, 86)

The reader knows that Claudius will contribute something to either his own demise or the death of the other characters. In this sense, the reader is led along through the story.

Hamlet also pronounces his distaste for his mother's marriage to his uncle in this scene. It is likely that she too will either be killed or have some role to play in the main character's insidious actions.

My father's brother, but no more like my father

Than I to Hercules: within a month:

Ere yet the salt of most unrighteous tears

Had left the flushing in her galled eyes,

She married. O, most wicked speed, to post

With such dexterity to incestuous sheets!

It is not nor it cannot come to good:

But break, my heart; for I must hold my tongue (Shakespeare,...

It is clear that Hamlet has some doubt as to whether or not his mother had something to do with his father's death. He finds it suspicious that his mother and uncle were married so quickly. At this point no thought is necessary. The tragedy is restful.
Also, the ghost obviously has important information to reveal to Hamlet. His friends urge him not to go and listen to the ghost. Perhaps they inwardly feel that something is amiss. The news told by the ghost will negatively influence Hamlet. In the true spirit of a tragedy, Hamlet doesn't listen to his friends. Readers know at this point that the stage is set for a most horrible tragedy.

My fate cries out,

And makes each petty artery in this body

As hardy as the Nemean lion's nerve.

Still am I call'd. Unhand me, gentlemen.

By heaven, I'll make a ghost of him that lets me!

I say, away! Go on; I'll follow thee (Shakespeare, 20)

Next, the dreadful information is revealed and Hamlet is transformed. Hamlet must kill his own uncle, however we know that something more will occur in this tale. Because the play is a tragedy, one knows that Hamlet will not simply avenge his father's death. Hamlet is sure to meet his end as well as some of the other characters in the play. However, it is arguable whether or not everyone's fate is known. The reader does know that death will befall on the characters. The reader does not know that something evil will become of the characters, especially those who are innocent in the matter. However the reader must sit and puzzle over how the acts will occur. They must piece the entire puzzle together. There is work associated with reading a tragedy because a reader must open his or her mind in…
