High Notes in the Voice
Most boring speakers speak in a monotone. Most famous actors use many notes in their voices. It is often how they leap from note to note that so astonishes us, the way they can vocally realize Shakespeare's antithetical thoughts so quickly and clearly. The high notes in the voice are where surprise and delight, wonder and questions reside.  They are also essential for comedy. The voice doesn't rest on them, it just plinks them when it when prodded by thoughts.

Sometimes when I can't get a student to realize how amazing or surprising or even funny a thought is, I ask them to put an operative or descriptive word on a high note. On occasion, the high note can help teach the thought.

A very large woman has mistaken Dromio for her husband and is lustfully persuing him. Dromio is describing her to his master. Inventing the bold words on high notes will help reveal the wonder and horror he feels. Those notes will also make him far funnier!

Merry, sir, she's the kitchen wench and all grease;
and I know not what use to put her to but to make a lamp of her
and run from her by her own light.
I warrant, her rags and the tallow in them will burn a Poland winter:
if she lives till doomsday, she'll burn a week longer than the whole world.
Her complexion is swart, like my shoe, but her face nothing half so clean kept.
Nell is her name.
She bears some breadth sir, no longer from head to foot than from hip to hip:
she is spherical, like a globe; I could find out countries in her.
Where Ireland? Marry sir, in her buttocks. I found it out by the bogs.
