Chest Voice? What is it?
Is it a voice that is somehow in the chest? Nope. The sound or texture that is associated with chest voice is still produced by muscles (arytenoids and vocal cords) located in the laryngeal area in the throat. However, there are sensations in the general area of the chest cavity that gave rise to the term.
The chest voice is a texture of sound produced when the arytenoid muscle system is mostly isolated. The “chest voice” is found or can be accessed when one sings at the bottom of the range, uses an increased volume, and forms a good [ah] vowel. One might think of chest voice as being the basement of our vocal home. It is a necessary part of our home as it hopefully includes the foundation, but it is not a part of the house that you would live in for extended periods of time!
Now, as the chest voice or closer muscle starts to coordinate with the falsetto voice or stretcher muscle, there is a different texture of sound produced called the full voice. We think of it like coming up the steps and going from the basement through the foundation area to the first floor. We feel we are standing above ground, sturdy and safe.
The characteristics of a chest voice that has not been coordinated yet are feelings of being a bit wild, gruff, raw, loud, buzzy, deep & heavy. There might also be feelings of scratchiness if overused, sometimes constrictive if weak or damaged.
When the closer muscle does begin to coordinate, the textural qualities are transformed; tame and powerful without overloading the vocal system. For we do not want excessive size and weight to cause the cords to buckle and open under force.
The closer muscle is responsible:
