Should the vocal position of Bel Canto be put back?

Hehe, actually, it sounds very strong that the timbre and * * * aria are at work, but the real Italian Bel Canto requires the sound to be in the front, and all the cavities are used together to send the sound to the head cavity to the maximum extent, and make a sound with good metallic feeling and penetration. The voices of Liao Changyong and Domingo mentioned by the landlord are also ahead, but each has its own voice and timbre, but it will never change. This "Sect" is the so-called "front", and the so-called "back" only requires opening the throat and keeping a relatively vertical space in the mouth. If the position is emphasized, the voice will be stagnant, empty and difficult to sing. If you emphasize the front, it will also cause the sound to be sharp and straightforward, lacking a sense of roundness and three-dimensional sense. Therefore, the truly beautiful voice is the combination of "before" and "after", which is obtained through constant coordination.
