The voice box is called the "Larynx", and is situated within the "Adam’s apple". It contains the two vocal cords. The vocal cords vibrate to make specific sounds, just like the reeds in a wind instrument, or a gum-leaf. Muscles move the vocal cords to change their position and tension, modifying the sound. The throat (pharynx), palate, tongue, mouth and lips modify the resonance of the sound to vocalise words or song.
