Does anyone know a gap in Macbeth that can be filled with a monologue? Any ideas will be great.I really need help with my English assignment...

One of the most famous "gaps" in the play is the murder of
Duncan.  The murders of Banquo and Lady Macduff are dramatized in the play, but the
murder of Duncan in Act II, scene ii, is an off-stage event.  There are two visits to
Duncan's bedchamber, one made by Macbeth when he actually murderers the king, and then
Lady Macbeth goes back to return the daggers to the scene of the crime.  Either of these
visits to Duncan's bedchamber would make a good
soliloquy.

Another much discussed gap is the change that
comes over Lady Macbeth from her exit in Act III, scene iv until she re-enters the play
in Act V.  How does she change from the assertive and confident woman of early in the
play to the guilt-ridden sleepwalker of the end?  This gap would be a good opportunity
for a monologue too.

The links below will give you more
detail about the scenes I have mentioned.  Good luck with your
assignment.
