____
* formed by the true vocal cords and the opening between them

A

true, expiration

28
Q

____ of a sound

* ⇧ tension → ⇧ pitch (higher noted)
* ⇩ tension → ⇩ pitch (lower noted)

A

Pitch (musical tone)

29
Q

____ of a sound
* the force of air passing through the vocal folds during expiration
* Stronger blasts of air → louder sound
* Weaker movements of air → softer sound

A

Intensity (loudness)

29

* vibrate more slowly
* voice becomes deeper

A

longer and thicker

30
