1. Use the "I" in the sliding sound and sliding sound to slightly open your mouth, open your chin, lift the smiling muscles, and move your chin down slightly to your neck. The neck and the back of the head stand upright, the soft shoulders in the mouth are propped up upwards, and the sound of I and U sliding seems to be the sound of a fire truck, which is even, stable and long in strength. When you make a sliding sound, it feels like a rubber band, which enters the head cavity from the junction of soft and hard waist along the posterior pharyngeal wall and finally comes out from the eyebrows; When you make a sliding sound, it feels like a sound (strong band) flowing from the center of the eyebrows along the posterior pharyngeal wall to the hard waist, and then rushing to the nasal cavity and sinuses at the junction of the soft and hard waist. Every time I practice, I use this feeling that the nasopharyngeal cavity is full of sound waves to practice pronouncing words or reading poems or singing. This exercise can exercise the vocal cords to close well, avoid air leakage, and make the sound solid, concentrated and bright.
Second, hum along with the slide.
Imagine the feeling of shouting a piece of candy in your mouth, close your lips slightly, relax your tongue against your lower teeth, separate your upper and lower teeth, lift your upper waist, keep a feeling of Gherardini, and straighten your neck. Then take a deep breath. When inhaling, pay attention to the feeling that the breath enters the breathing cavity smoothly, and keep this state of nasal cavity expansion. Then, using the strength of the abdomen to make a soft and long sliding sound, at the same time, consciously guide the sound through the upper jaw of the mouth, upward along the posterior pharyngeal wall, and smoothly pass through the front (mask), middle (olfactory inlet) and back (nasopharynx) of the nasal cavity to reach the frontal sinus and sphenoid sinus. When practicing, we should carefully understand the role of * * from the upper nasopharyngeal cavity. Every time I practice, I practice voiced syllables with the initials m and n, such as "Ma", "Mi", "Mail", "Mei", "Mi", "Na", "Nai", "Inner" and "Female".
3. Chew with the long sound of "a ……", and with the natural pitch of your usual speech, make a full, smooth and long "M" sound easily and naturally. While chewing, you will keep moving your jaw like chewing gum. When pronouncing, you should carefully experience the feeling of relaxation of chin and throat muscles. The sound is concentrated in the oropharynx and then spreads to the sides of the nose and the upper part of the rest beam to produce vibration. Every once in a while, you can naturally open your mouth vertically and drive out "A" with soft "hemp" ..........................................................................................................................................
When you practice to a certain degree of proficiency and can accurately grasp the position, you can omit the driving of the middle "horse": "m … m … m … m … m … m … m … m … m … m … m … m … m … m … m …" Pay attention to reading aloud without seeking to increase the volume and express the content of the text, but carefully understand and consolidate the comfortable sound position and the feeling of vibration above the mouth.
And other methods to consolidate, and then gradually increase the volume, inject feelings, the pursuit of beautiful soft and bright timbre. This exercise can not only find the timbre of the high position in the sound concentration, so that the breath will not be wasted, but also keep the position of the larynx restored and relatively stable, and achieve the effect of obtaining the maximum * * * sound with the least intensity.
