What do you mean by 'dampen' exactly? Do you call shortening (as opposed to
lengthening) of the cords dampening?

When I think of dampening I think of taking a cloth to a ringing bell or
palming a guitar string or pressing the 3rd piano pedal. I don't see how it
applies to the vocal cords. I would like to understand this concept.
