Figure 7 shows the under jaw relaxed, as it should be in practice, to enlarge the throat and give roundness and largeness to the tone. The use of the word hung will accomplish this end.

CHAPTER III
Breath Control
It has been said that "breathing is singing." This statement is equally applicable to speaking. While the aphorism is not literally true, it is true that without properly controlled breathing the best singing or speaking tone cannot be produced, for tone is but vocalized breath; hence in the cultivation of the voice, breathing is the first function to receive attention.
For singer or speaker, the correct use of the breathing apparatus determines the question of success or failure; for without mastery of the motive power all else is unavailing. For a voice user, therefore, the first requisite is a well-developed chest, the second, complete control of it.
