We all want to have a clear and beautiful voice. Let me introduce you to the resonating organ of voice. The human vocal cords vibrate to produce the original laryngeal sound (fundamental sound), which is amplified and beautified by the resonance cavity to make a pleasant voice and song. The resonance organs are divided into two parts: the upper part includes the nasal cavity, sinus and nasopharyngeal cavity, and the lower part includes the laryngeal cavity, pharyngeal cavity, oral cavity and thoracic cavity. Among them, the shape of the pharyngeal cavity and oral cavity can be adjusted to become adjustable resonance cavity, is the main part of vocal training. The nasal cavity and sinuses, etc. as a complement to the vocal tract resonance, for non-adjustable resonance cavity. The tongue, palate, lips, teeth, cheeks, etc. in the oral cavity play an important role in the composition of the voice, by adjusting the relative position of these structures, changing the shape and size of the oral cavity, so that the voice is clear, and different vowels and consonants are issued
. According to the different resonance parts and pitch can be divided into: 1, cephalic (cranial) resonance: that is, high resonance, including the nasal cavity, nasopharynx, sinuses, etc., so that the voice is bright, rich, rich metallic clanging color. 2, thoracic resonance: bass resonance, including trachea, bronchus and lungs, etc., so that the sound is bright, thick and powerful. 3, oral resonance: for the alto resonance, including the oral cavity, oropharyngeal cavity and laryngeal cavity, etc., so that the voice is bright and clear, but also the main organ of singing resonance. Among them, the laryngeal cavity is not only the articulation organ, but also involved in the role of resonance. The laryngeal cavity is lifted to shorten the resonance cavity, while the laryngeal cavity and the interventricular cavity act as a transducer or filter for the original vocal hilar sounds. Vocally, all three resonances are required to function when singing. However, different vocal parts are dominated by one type of resonance. Individuals have different timbres due to their gender, age, larynx and resonance cavity structure, and therefore have different overtones, so we can distinguish each person’s voice by voice. Sound from the vocal cords, through the laryngeal cavity, laryngeal mouth, pharyngeal cavity, and then through the oropharyngeal cavity and nasopharyngeal cavity, to reach the nasal cavity, at this time, the sound rushes up the nasal cavity along the back of the soft palate, in the back of the nasal cavity back, to get this part of the resonance, sound through the mouth by the mouth, will also have a special tone of nasal resonance. The sound reaches each resonance cavity and gets the resonance boost step by step, and finally when the sound comes out from the mouth, the sound quality has been greatly embellished and the volume is gradually enhanced. In the process from the vocal cords to the mouth, the more places we meet with resonance conditions, the more resonance assistance we get, the brighter the sound will be, and the more ideal the tone will be.
