Chapter 9
Summary
-This chapter indicates and explains all of the muscles and parts of the body that go into making articulation happen. The muscles in the tongue are responsible for vowel shape. The tongue (dorsum) consists of intrinsic and extrinsic muscles that are connected to other parts of the head and can therefore affect the jaw, larynx, and vocal tract. The extrinsic muscles include the palatoglossus, styloglossus, genioglossus, hyoglossus and are responsible for raising the posterior of the tongue and lowering the soft palate. They help with contraction and depression of the tongue and must be as free of tension as possible for efficient phonation. The Pharynx and Palate are just fancy words for the inside of the mouth and all the parts that are involved including the soft palate, hard palate, uvula, fauces, tonsils, and pharynx. The pharynx specifically is made up of different muscles including the superior, middle, and inferior constrictor muscles in addition to the levator palati, tensor palati, palato pharyngeus, palatoglossus, and the musculus uvulae. These muscles are responsible for swallowing, helping with the tongue, narrowing the pharynx, and lowering and elevating the soft palate. The jaw is one bone called the mandible that is attached to the skull. Having TMJ syndrome can make moving the jaw a lot more difficult. The jaw is used for articulation as well as chewing. The muscles used for opening the jaw are a lot weaker than the ones used to close the jaw. The biggest muscle that is responsible for jaw action is the temporalis. Having a loose jaw free of tension is desirable for singing. All of these muslces are connected so it is difficult to do one thing without affecting another muscle group. Learning to sing well with this depends on being able to use things independently.
Application
-Knowing all of the different muscles and connections, what they are called, and how they work is important in being able to identify and relieve tension in ourselves and in our students.
