"High" means that the position of the voice (the first sound of the head cavity) should be high, that is, always sing in a high position to obtain a good singing voice. Bel Canto singing should be full of sound. In fact, different songs and different registers have different emphasis on the use of vocal tone when singing. We require the singing position to be uniform and high, and to sing with the head cavity.
When the vocal cords vibrate at a certain frequency, if the sound production method is accurate, the vibration of that frequency can be produced. The proportion of octave frequencies is very small, and there are no other frequencies (noise). At this time, the frequency is distorted The distortion is very small (if the distortion is large, the sound will sound "hairy"). Similarly, after the sound passes through the resonance cavity, the sound frequency obtained by applying the correct resonance method is only that frequency and its multiples. In this way, all the energy of the sound is concentrated on this frequency and its multiples, making it clear and pleasant to hear and transmitted far. The high position is a way to achieve this goal. The airflow is bundled and strongly impacts the tubular sound source to produce vibrations of a certain frequency, resulting in pure sound. It is not easy to produce lateral vibrations (perpendicular to the main frequency vibration direction) during transmission. When singing at a low position, the airflow beam is not stiff, and it is difficult to excite a single frequency when the vocal cords are vibrated. When transmitted, it is easy to become diffuse, the frequency distortion is large, and the energy is not concentrated. The sound isn't very clear, and it doesn't travel far. To reach a high position, one of the keys is breath support, while mainly using the head cavity to sing.
"Light", volume control. When the machine is working at full load, it vibrates violently, makes a lot of noise, and is easily damaged. People are also prone to fatigue when working at full capacity. A man who can only carry a load of one hundred kilograms always gasps and staggers forward while carrying a load of one hundred kilograms. Fashion models carrying heavy loads cannot walk gracefully in catwalks or pose seductively. Moderate load keeps people or machines in good working condition. Controlling the volume and singing softly not only allows the singer but also the audience to enjoy the beauty, and the pitch and timbre are easy to control. But "light" is relative. If you exercise enough to be able to lift three hundred kilograms, then lifting one hundred kilograms will become easy. In singing, this kind of training is to master the correct method of vocalization and singing. High-level singing must be supported by strong breath, which is the basic point to achieve easy control of soft voices. Such soft sounds are positive, the music has a sense of flow, and the mood is full.
"Soft" reflects the control of timbre and volume. The sound is neither too bright nor too dark. Timbre, from a sound perspective, is related to overtones. Overtones generally refer to other octave tones (multiples of the fundamental frequency) other than the fundamental tone. Usually when the fundamental frequency vibrates, it is often accompanied by high-frequency sounds such as double frequency, triple frequency, etc. The higher the frequency, the weaker the sound. Even-numbered octaves are basically octaves in music, and odd-numbered octaves are fifths. The overtones do not necessarily include two, three, and four times the frequency. Due to the different mastery and methods of singing tunes, In particular, the breathing method will affect the sound of a certain octave that is particularly prominent while the other octave sounds are too weak, which may form what Professor Shen Xiang said is "too bright" and not soft.
"Soft" is not soft or weak, it is the control of timbre and volume. It is closely related to the purity of the fundamental tone and the method of singing, which in turn is closely related to the support of the breath.
"Soft" also includes a sense of fluidity and elasticity in the sound. "High, light and soft" adapts to people's needs for sound in modern society. In other words, modern songs (mainstream) are suitable for singing with "high, light and soft" voices.
"Beautiful", beautiful voice, emotional and moving singing. Let the audience feel the beauty of choral art, which is closely related to high, light and soft. In fact, high, light and soft are just the basis and conditions for achieving beautiful sound. What really makes the audience feel beautiful is the singer's deep understanding of the song, expressing the connotation of the work through vocal skills, and inspiring the audience with both voice and emotion. This is what music artists particularly emphasize. Perfect reproduction of the choral art gives people a sense of beauty. The enjoyment of beauty is also the purpose we pursue.
