HAMLET
Why, look you now, how unworthy a thing
you make of me! You would play upon me, you
would seem to know my stops, you would pluck
out the heart of my mystery, you would sound me
from my lowest note to the top of my compass;
and there is much music, excellent voice, in this
little organ, yet cannot you make it speak. 'Sblood,
do you think I am easier to be played on than a pipe?
Call me what instrument you will, though you can
fret me, yet you cannot play upon me.
(3.2.393-402)
When Rosencrantz and Guildenstern try to get Hamlet to confide in them, Hamlet is super ticked off. He compares deception to playing a musical instrument to mock his frenemies for not being skilled enough to "play" him. Oh, and guess what? Their deception ends up getting them killed, too.

HAMLET
An earnest conjuration from the King,
As England was his faithful tributary,
As love between them like the palm might flourish,
As peace should stiff her wheaten garland wear
And stand a comma 'tween their amities,
And many suchlike ases of great charge,
That, on the view and knowing of these contents,
Without debatement further, more or less,
He should the bearers put to sudden death,
Not shriving-time allowed.

HORATIO
So Guildenstern and Rosencrantz go to 't.
(5.2.43-52; 63)
Hamlet is patting himself on the back pretty strenuously about how he got revenge on Rosencrantz and Guildenstern by sending them to their deaths. Totally fair, he says: they deceived him, so they get what they deserve.
