=Natural Quality= may be described as a head tone to which some degree of resonance is given by the chest; but the brilliancy of its resonance is produced by its reverberation against the bony arch of the mouth. It may, of course, vary in pitch, but tones of low pitch that are intended to be impressive are most suitably rendered in orotund quality. In its perfect manifestations, the natural quality should be clear, ringing, light, and sparkling,--if it be possible to describe its characteristics by such metaphorical words. =Orotund Quality= is the result only of cultivation, but no speaker or reader can produce those finer effects which are the appropriate symbols of strong and deep emotion, whose voice cannot assume this mode at will. It differs from the natural mode in obtaining from the chest a greater supply of air, and a deeper and fuller resonance, and the reverberations seem to be against the walls of the pharynx, or posterior regions of the mouth, rather than against the palate, or upper part of the mouth. In fulness, strength, and ringing quality, it is superior to the natural mode, but not distinct from it; in clearness and smoothness it should be equal to it. As it befits a chest tone rather than a head tone, it is natural to utterances in medium and low pitch; but it must not be confounded with low pitch simply, nor must its characteristic fulness be taken for loudness simply. With the orotund, as well as with the natural quality, all the voice modes previously described may be conjoined. EXERCISE.--1. With the syllable _haeh_, make an expiration in the voice of whisper, forcing slowly all air out from the chest. Then give to this expiration vocality, producing the reverberation far back in the mouth: the resulting utterance is a _hoarse exemplification of the orotund_. With the mouth in the position of a yawn, making the cavity of reverberation as large as possible, repeat the exercise until the utterance can be produced smoothly and without hoarseness. 2. Form similar syllables containing other tonic elements, and make similar exercises, taking care to produce a smooth, effusive utterance. 3. Select a sentence such as "_Roll on thou deep and dark blue ocean, roll_," abounding in long open vowels and indefinite syllables, and using suitable intonations read it in low pitch, with full, resonant chest tones. Then gradually raise the pitch, still obtaining the tones from the chest and uttering them with full resonance. 4. With such syllables as _haeh_, _you_, _now_, _man_, _war_, _hail_, _fool_, practise in orotund voice the various exercises for pitch, concrete intervals, waves, stress, etc., previously suggested. 5. Read with feeling and appropriate intonations selected sentences from compositions of elevated or impassioned diction, as "Solomons's Prayer" (p. 35), "The Hymn" (p. 68), "France" (p. 205).
