Yet as brilliancy and point are more native to the high notes, nasal resonance is always more marked in this part of the voice. In the same way the qualities of tone due to chest resonance belong more properly to the lower and middle tones. On the practical side this is of great importance. It is vastly more easy to secure command of each form of resonance first in that part of the voice to which it is native. When this has been done it is a comparatively simple matter to extend this command higher or lower as the case may be. It is the usual practice to begin instruction in the management of resonance with the mouth-pharynx cavity. For this purpose exercises on the vowel _ah_ are generally first used. The position assumed by the tongue for this vowel is peculiarly favorable for securing an expansion of the lower part of the mouth-pharynx cavity. An increase in the size of this cavity is sought for the purpose of bringing about a corresponding increase in the volume and power of the tone. While not directly a feature of mouth-pharynx resonance strictly speaking, the emission of the tone is usually treated under this head. After being generated by the vibration of the vocal cords, the tone is to be directed to the front of the mouth, in such manner that it impinges on the hard palate, just above the upper front teeth. This has for its purpose the freeing of the tone from the vocal cords and the bringing of it forward in the mouth, so as to secure the effect of ‘forward tone’ advocated by the old masters. For acquiring the effect of forward tone, studies are also used on tones begun with certain labial and lingual consonants. Exercises are given on single tones on such syllables as _bah_, _bee_, _boo_--_ma_, _mee_, _mo_--_la_, _lee_, _lo_, etc. These are practised on notes covering a range of about one octave. Similar exercises are used for obtaining command of nasal resonance. For this purpose the consonant _n_ is especially favored and exercises are used on syllables such as _na_, _nee_, _no_, etc. Another means of acquiring command of the several forms of resonance is found in certain characteristic sensations which the singer experiences in singing tones of the various types. A tone strongly marked by nasal resonance awakens a sensation of tingling in the forehead and upper nose. A pronounced feeling of vibration in the upper chest, particularly in the region of the breast bone, accompanies the right use of chest resonance. The ‘forward’ tone is characterized by similar sensations in the front of the mouth. When practising exercises for acquiring command of resonance the student is instructed to feel the appropriate sensations, thus bringing the tone into the proper position.
