The vocal cords are formed by folds of the laryngeal mucosa of about 2 cm in length located in the larynx. These are the organs which enable noise emission, from a simple cry to the most sophisticated communication, including song. Breath vibrates the vocal cords and leads to the formation of sound. Depending on the position of the lips, tongue, and the power of breath, the vocal cords form vowels or consonants in the bass or treble clef, voiced or unvoiced. The vocal cords are the main instrument of oral communication and one of the characteristic organs of the human race.
