Assistant Professor Bethany Worrell recently led her University of Missouri–St. Louis music students through an exercise designed to help them visualize the way their bodies produce sound.

Worrell, UMSL’s director of vocal studies, called the exercise “Anatomy in the Round: Acting Out the Larynx.” Each student was assigned a role to play as they constructed a human-size model of the larynx, complete with 9-foot vocal cords, and they acted out multiple vocalisms in Whitaker Hall in the Blanche M. Touhill Performing Arts Center. UMSL campus photographer Derik Holtmann was on hand to capture photos and video of the activity.
