There’s no art to find the play’s construction in the verse.
MacBeth and friend Banquo o’erwhelm Cawdor’s Thane;
Three witches predict bold MacBeth soon shall reign.
The Lord and his Lady slay Duncan the King;
Ambition unfettered, dark torment doth bring.
Cunning Weird Sisters unveil Banquo’s line;
MacBeth instigates a most murderous design.
Now vengeful MacDuff with great Birnam Wood comes;
MacBeth’s time plays out with blades, blood, death and drums.
