Are the lungs connected to my voice?
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 chords, 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 chords: if you almost close the space between your vocal chords, 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 shape these sounds into words.
