Inside the larynx are present two pairs of vocal cords. One pair is of false vocal cords which has little to do with sound production and the second inner pair is true vocal cords. When air is forced through the larynx, it causes vibration of the true vocal cords and sound is produced. The pitch of sound is determined by the tension on the vocal cords-the greater the tension, the higher the pitch.
