It can be distinguished by unclear articulation, lack of breath, raised Adam's apple, etc., as follows:

1. Unclear articulation

It is characterized by ambiguous pronunciation of words. Unclear and lacking intensity. The cause is due to poor control of the movements of the initial consonants. When articulating words, the lips, teeth, tongue and other articulation organs fail to actively coordinate their movements, resulting in the inability to boldly enunciate words. The tip of the tongue is weak, and the larynx does not block the air downwards. In addition, if the throat is too wide, it will also affect the pronunciation.

2. Not enough breath

This is a common vocal error, which is manifested in the inability to sing a song completely, always feeling that there is not enough breath, and struggling to breathe. , physical exertion is high, it is difficult to control the sound, and the sound is often low. The reason is mainly due to the weakness of the diaphragm and the muscles that control breathing, such as abdominal muscles, back muscles, pharyngeal muscles, etc., and secondly because the vocal cords are not closed tightly.

3. Lifting of the Adam's apple

This is the most taboo problem in singing. The symptoms are that the voice is crowded and tight, the throat sound is very heavy, and high notes are especially difficult. The reasons can be divided into three types: the physical structure of the Adam's apple is too high, and the Adam's apple is blocked as soon as the voice is produced, and its activities are restricted. This situation is not suitable for studying vocal music majors;

Usually the position of the Adam's apple is not high. , the low-pitched area is still stable, but as the pitch of the Adam's apple rises, the Adam's apple can still move up and down. It turns out that the Adam's apple is stable. Due to the wrong learning method, the larynx is trained up, and people cannot control it. The latter two can be overcome through hard work and correct singing methods.

4. Vibrato

Vibrato is a small tremor, which is characterized by irregular trembling of the voice. The reason is that the larynx is unstable and shakes, and the muscles of each vocal organ are out of control.

Extended information

The cause of tone deafness is congenital. It is not out of tune or out of tune as commonly said. Out of tune can be corrected, but tone deafness is difficult to completely correct. The cause of tone deafness is that the muscles around the vocal cords are not fully developed, resulting in the inability to pronounce some pitches. Another cause is the poor ability of the ears to distinguish sounds, resulting in inaccurate pronunciation. The latter type can be improved or even reach the level of normal people through training, while the former type is basically unchangeable.
