"Tomorrow and tomorrow and tomorrow" is the beginning of the second sentence of one of the most famous soliloquies in Shakespeare's tragedy Macbeth. It takes place in the beginning of the 5th scene of Act 5, during the time when the English troops, led by Malcolm and Macduff, are approaching Macbeth's castle to besiege it. Macbeth, the play's protagonist, is confident that he can withstand any siege from Malcolm's forces. He hears the cry of a woman and reflects that there was a time when his hair would have stood on end if he had heard such a cry, but he is now so full of horrors and slaughterous thoughts that it can no longer startle him.
