What is the title's meaning The Sound and the Fury?

The title Sound and Fury came from the famous soliloquy from Macbeth by Shakespeare:

"Tomorrow, and tomorrow, and tomorrow,

Creeps in this petty pace from day to day

To the last syllable of recorded time,

And all our yesterdays have lighted fools

The way to dusty death. Out, out, brief candle!

Life's but a walking shadow, a poor player

That struts and frets his hour upon the stage

And then is heard no more: it is a tale

Told by an idiot, full of sound and fury,

Signifying nothing" (V.v in Macbeth).

The title can be interpreted in many ways. It was said that William Faulkner based the whole book on this soliloquy. For example, all the shadow and light motifs may have originated from this soliloquy. "A poor player that struts and frets his hour upon the stage and then is heard no more" could refer to Quentin's story because he is constantly obsessed with time before he commits suicide and is "heard no more." Although very harsh, "it is a tale told by an idiot, full of sound and fury" may even refer to Benjy's narrative because of his inability to distinguish time. The sound and fury may be the moans Benjy makes and his inability to communicate. However, it may also be about the other characters... such as Jason's fury!

There are so many different interpretations! .. But here's a little blurb about the origin of the title to help get you started!
