Want it. The active parts of the tongue are mainly at the tip of the tongue and the middle of the tongue. The general rule should be that after the tip of the tongue gently touches the lower teeth, the base of the tongue and the lower jaw relax and the throat remains relaxed. The diaphragm is used to effectively maintain the respiratory support of the lower abdomen, open the throat, stabilize the larynx, and pay attention to the sound of the high mask. After the sound comes out of the throat, it touches the junction of soft palate and hard palate, then passes through the nasal cavity and touches the eyebrows. The pharyngeal wall is required to stand upright, with special emphasis on the use of head singing.

In the process of vocalization, the singer's chest and head cavity should be used, and his main attention should be paid to the head cavity. Only those who are "good at sending voices to the head cavity" are really singing. The change of acoustic cavity caused by tongue-the extension of the tongue enlarges the pharyngeal sound, and at the same time, because the root of the tongue is associated with the soft palate, the extension of the tongue pulls the palatine tongue to move the soft palate forward. The change brought by the improvement of the middle and back part of the tongue is not only that the mouth becomes smaller, but also that the distance from the throat to the nasopharyngeal cavity is shortened because of the thyroid bone. It can be seen that the movement of the tongue has a great influence on the sound. Generally speaking, the singing method of head cavity is very important for high notes. The specific way is to let go of the lower jaw and roll the tongue naturally, so as to widen the passage between the mouth, nose and pharynx, and make the sound waves spread to the nasal cavity and forehead along the maxilla.

If the tongue moves backward too much and lifts up too much, the vocal tract will become smaller, and the sound is likely to get stuck behind the base of the tongue and cannot reach the nasal cavity, thus entering the head cavity to form a mask. There is no way to say that the human body is singing, so we should not only release the sound from the throat to the mouth, but also find the sound point in the mouth.

And the sound point I summarized is in the middle of the front end of the tongue. This position just allows the sound to reach the nasal cavity, so as not to hinder the sound transmission, release the sound from the throat, let the chest communicate with the oral cavity, then lower the throat to relax the oral cavity, let the sound release from the throat and then enter the head cavity, and then spread from the nasal cavity to the oral cavity, forming what we call a mask.

Never sing backwards or downwards, because the sound comes from the front of the mask. The sound is always concentrated where the forehead meets the nose. This sense of vibration and head ringing is necessary in any form of singing. Forward sound is one of the main goals pursued by singers. It just tries to aim the sound at the front of the mouth and behind the front teeth.

These predecessors all told us what the position of sound is, that is, the position of sound in the mouth should be in the front, and laryngeal sound will be formed in the back. This method of vocalization is incorrect, which affects the production of human vocalization, resists the vocalization of the mask, and makes the voice fail to play a good role. Therefore, we require the voice of * * * to be connected up and down, which requires our voice to be in the front of the mouth.
