yep, the scene where caliban is reassuring the drunken stephano and trinculo not to worry about the tune Ariel is playing to scare them. It's one of the most beautiful speeches, even though it is paradoxically the "beast" of the island who says it.
"Be not afeard; the isle is full of noises,
Sounds and sweet airs, that give delight and hurt not.
Sometimes a thousand twangling instruments [140]
Will hum about mine ears, and sometimes voices
That, if I then had waked after long sleep,
Will make me sleep again: and then, in dreaming,
The clouds methought would open and show riches
Ready to drop upon me, that, when I waked, [145]
I cried to dream again."
Interesting to have a bit about a "thousand twangling instruments"!
