[CHAPTER XX.]
REVIEW AND REVISION.
The object of the speaker or singer—The idea of co-ordination—The study of vocalization may be considered a study of movements—The psychic condition—The instrument which is played upon—How is this instrument played upon?—Vibration of the air—Breathing—The aim of all training—The whole subject of breathing—Breathing exercises—The resonance chambers—The formation of vowels—Muscular efforts for the production of consonants—The pronunciation of words—General health of great importance [276]
