Summary:
This chapter talks about the structure and function of the larynx, the vocal folds and their various parts. He discusses the vocal folds which are composed of layers including (from outer to inner layers) the epithelium (which is covered in mucus), the lamina propria and the thyroarytenoid muscle. This layering allows the folds to oscillate with the assistance of airflow. The larynx, where the vocal folds are found is made up of muscles and bones. There are muscles that close and open the glottis, shorten/thicken the folds, and lengthen/thin the folds.
Analysis:
Understanding not only how the vocal folds work, but how they interact with the respiratory system is incredibly interesting and helpful for many reasons. For one thing, it helps me understand the directions given by my vocal therapist and helps me interpret the images they send me home with. It is also good to know as a teacher, what is happening in the vocal mechanisms of my students. This can help me isolate and create exercises that might find the more efficient result we're looking for. For example, I've been having a hard time in my own lessons finding a balance between my breath and musculature in my larynx which is resulting in over or under pressurization. Understanding what is happening in my body is helpful because it gave me ideas for exercises to try. It also made me see my voice as an instrument that can be guided and manipulated, rather than a direct reflection on me.
