while a weak voice is incompatible with first-rate excellence in delivery. For we may employ a good, strong voice as we will; whereas one that is ugly or feeble not only prevents us from producing a number of effects, such as a crescendo or a sudden fortissimo, but at times forces faults upon us, making us drop the voice, alter its pitch and refresh the hoarseness of the throat and fatigue of the lungs by a hideous chanting intonation.

The first point which calls for consideration is the nature of the voice, the second the manner in which it is used. The nature of the voice depends on its quantity and quality.
