What is the tolling of the ebony clock meant to symbolize and how does the sound make the members of the affair feel? I NEED MAJOR HELP!!! I'm a...

The clock is symbolic of the passing of life.  It's tolling means that the party (life) will soon be over.  Also, note that the clock is "ebony," black, traditionally a symbol of death.  However, the revelers take little heed of its stern warning, even though Prince Prospero is begging them to listen.  The party-goers think they are safe in the castle, away from the "red death" that is killing hundreds outside its protective walls.  The lesson here is that none will escape death, but many people just don't want to realize (or are too foolish to understand) that the party is definitely over.  No one escapes death.
