Yes. The human voice, whether singing, speaking, or yelling, is made by a combination of factors. It all begins with air. Air from your lungs rushes through your trachea (also called the windpipe) and vibrates your vocal cords, a tiny, two-part muscle located in the larynx (also called the voice box) in your throat. The pitch of the note depends on the distance between the vocal cords. If you almost close the space between your vocal cords, the result is a high-pitched sound. If you open the space, the result is a low-pitched sound. And the speed of your breath determines just how loud the note is. Your lips and tongue help to shape these sounds into speech and other expressions.
