Increasing the tension on the vocal cords allows them to vibrate at a higher frequency and produce a higher pitch. Changing the force of the air passing over the vocal cords can also affect pitch, but increasing tension is the primary way singers hit high notes. Changing the size or shape of the laryngeal cartilages is not a conscious control for most singers and is not a reliable way to hit high notes.
