Rising inflection is used in incomplete thought, or thought carried
through consecutive phrases. It is used to express emotion, surprise,
prayer.
Falling inflection denotes complete thought. It expresses command,
authority.
The voice has three pitches:--upper, middle, lower.
The upper register is the medium for the expression of excitement and
earnestness. It must be used with care and artistic moderation,
otherwise it is unpleasant.
Use it rarely. Be careful of straining the voice.
The middle register is used in familiar speaking, and general
conversation. It is the most durable, and is the vehicle for everyday
use.
The lower register is suited to grave, solemn, impassioned utterances.
It should be used cautiously. Practice will mellow the voice.
