Estill Figure

The Estill Figure, also known as the "Estill Figure," is a visual diagram used to illustrate how different voice and speech muscles work together during various vocal techniques. It offers a detailed map of the anatomy involved in voice production, highlighting key structures like the larynx, tongue, and jaw. By understanding these muscle functions and their positioning, singers and speakers can learn to control their voices more precisely, improving quality, range, and style. Essentially, it’s a useful tool for visualizing the complex coordination required for healthy, expressive vocal performance.
