The âfalseâ vocal folds or cords are placed above the real vocal cords and prevent the substances like food from entering inside trachea while we are swallowing it. They are not in any way related to the function of singing or speech.
The arytenoid cartilages, which anchor the vocal cords at the rear of your larynx, play a major role in tightening and moving your vocal cords in and out to vary the pitch of the sounds you make.
