(1) The mouth must be well opened.
(2) The vocal aperture must be large.
(3) The jaws must be flexible.

If the mouth is well opened the tones are full; if partially
closed they are muffled. The vocal aperture is the opening in the
rear of the mouth produced by the elevation of the uvula, and
the depression of the root of the tongue and the larynx. The
purity and richness of the voice depend, to a great extent, upon
the capacity of the vocal aperture. If it is of small capacity, or
contracted, the tones are impure and nasal.

The mode of producing pure tones can be studied best before
a mirror placed so that the light falls upon the back part of the
mouth.

_Exercise I._ Open the mouth to the fullest extent and close
rapidly. Repeat.

_Exercise II._ Open the mouth to the fullest extent, so that
the uvula rises and almost disappears, and the root of the tongue
and larynx are depressed. The action is similar to yawning, and
to accomplish it "think a yawn", if necessary.
