Bel canto requires natural sound, loud and clear voice, beautiful and pure timbre, appropriate round and coherent * * * sound, extra heavy starting method, clever sliding sound, stable sustained sound, fading and regular decorative sound. Its purpose is to make the melody more gorgeous, flexible, mellow and brilliant, the pitch more accurate and the sound more penetrating. Rossini, a famous Italian opera composer, believes that bel canto should have three requirements: first, it should have a natural and beautiful voice, which can keep the voice uniform throughout the singing range. Secondly, after strict training, I can easily sing extremely gorgeous and superb music works. Thirdly, by listening to and appreciating excellent Italian singers, we can fully master the style of Bel Canto. These three requirements make a scientific and complete summary of Bel Canto. 17 and 18 centuries, bel canto was in a period of vigorous development, and eunuchs appeared in Europe, who pushed bel canto to the peak. In the history of vocal music, people call this period the golden age of Bel Canto. However, because their singing skills were too ostentatious, their singing was divorced from reality and lacked realism, with the development of society, especially after the French bourgeois revolution, people advocated the authenticity of art, and eunuchs were gradually eliminated and eventually withdrew from the historical stage. After entering the19th century, bel canto has made new progress. Italian operas represented by Rossini, Donizetti and Bei Lini and French operas by Meyer boldly adopted natural boys and girls instead of eunuch singers. By the middle of19th century, aria in opera had become an important part of Bel Canto. At this point, vocal music singing has become the fashion and trend of vocal music technology development with its more masculine, impassioned and powerful voice.

China's vocal music is based on our own aesthetic habits, pronouncing words according to Chinese pronunciation, absorbing the advantages of western Bel Canto singing on the basis of traditional opera singing and folk song natural singing, and calling the vocal skills used in singing folk songs and songs with strong national style national singing. For thousands of years, our ancestors created splendid and civilized music culture and beautiful folk songs. From Wind, Elegance and Ode to today's new folk songs, they are all the crystallization of the wisdom of working people. At the same time, it also produced a unique singing style. The earliest folk songs in China were basically sung in pure tones (people call them loud voices). This way of singing is real and natural, which makes people feel cordial. Folk songs in some places in the north, such as "Flowers" in Qinghai, are sung in a falsetto in a high-pitched area, which is very distinctive. This primitive singing method is closely combined with language and has a strong local style, usually rap. Its sound quality is bright, and the sound is in the front position. This kind of voice has obvious shortcomings because of its shallow breathing, few * * * sounds and insufficient softness and roundness.
