Perhaps
staging the scene of Lady 's manipulation of her husband as she asks him to dig deep for his
courage could visiualize the  of her speech:

And we'll not fail. Whenis asleep

Whereto the rather shall his day's hard journey
Soundly invite himhis two
chamberlains
Will I with wine and wassail so convince,
That memory, the
warder of the brain,

Their drenched natures lie as in a death,

The unguarded Duncan? What not put upon
His
spongy officers, who shall bear the guilt
Of our great quell?(1.7.68-80)

Certainly, appropriate music would suggest the sinister and unnaturalness of the acts to be
committed.
