I'm a speech language pathology student. Can you believe something like that is in your throat?! This amazes me. Not only are the vocal folds vibrating at intense speeds (Hz) but the very walls of the larynx are shaping the sound.

And to dd, we might not be able to see the folds close in high notes because the strobe light might not have been set to be in sync with the hz of the note she was singing.

And as much as I worship John Barry, I like "Tomorrow Never Dies" better. Blasphemy, I know...
