He pioneered the circulation ventilation method of flute playing, pioneered and used the flute, created the L-shaped double bass flute, and personally designed and produced the ancient flute playing instrument "Pool". He initiated the theory and method of calculating the frequency of the flute, and composed and adapted more than ten flute solo songs, such as Fan Er, Xipi Flower Board, Partridge Flying, Busy Picking Tea, Youlan Feng Chun and so on, which were widely circulated. These music works have become the treasures in China's music art treasure house. At the same time, he published papers such as Origin of Bamboo Flute, Bass Flute and L-shaped Flute, Inheritance and Development of Flute Art in China, Double Flute in the Same Pipe, and edited and published works such as Broadcasting Lecture on Playing Skills of Bamboo Flute. From the aesthetic point of view, Zhao Songting advocates that "musical skills serve the expression of content, and what is divorced from content expression cannot be called skills;" Bamboo flute itself is constantly developing, and its skills should be constantly innovated; Skills, regardless of Chinese and foreign ancient and modern things, must be absorbed as long as they are helpful to content expression. "Although Zhao Songting's flute art comes from the folk, he didn't go to a music school, but his literary accomplishment and scientific knowledge are quite profound, so his teaching is systematic and scientific, the compilation of teaching materials is also quite concise and rigorous, and his disciples have a high success rate. Many of his students are well-known at home and abroad. Zhao Songting's only regret is that she didn't cultivate excellent female disciples. He said: "Most of the flute players in the Tang and Song Dynasties were girls. I plan to recruit a group of female students and explore whether there can be female flute players. "
In teaching, he attaches great importance to the cultivation of solid basic skills and artistic morality. He used vivid metaphors, and the artistic morality and skills he told made the students unforgettable. Sometimes, he will use humorous methods to encourage students to raise their awareness and enhance their confidence. He has a high literary accomplishment and rich historical knowledge. When talking with people, he can often quote classics and export them into articles. His flute skills are still in full swing at the age of seventy. He also personally participated in the performance and published the printed film "Selected Works of Zhao Songting's Flute" and "Ten Audio-visual Lectures on Flute Course". Zhao Songting has also conducted two studies. First, bending the pipe flute can increase the length of the flute without affecting the convenience of playing. The second is "two flutes in the same pipe", also known as "wild goose flute". When you play, your hands are flying like geese, which is very handsome and beautiful. This kind of flute is recorded in historical documents and can also be seen in murals. Now it has been invented and innovated by Lu and Lu of Qiqihar.
Zhao Songting inspected the bone flute unearthed in Hemudu, Yuyao, and concluded that the flute is the oldest musical instrument in China, and its history can be traced back to 7000 years ago. From ancient poems such as "whose Yu Di flies in the dark and the spring breeze fills the rocky mountains" and "Yu Di blows in the Yellow Crane Tower and plum blossoms fall on the river in May", he sprouted the idea of making a flute with jade to reproduce the national treasure. Yu Di, who has been successfully trial-produced, has been put into performance overseas.
In terms of jurisprudence, he believes that both pure law and peaceful law are indispensable and should not be fixed, otherwise the style will be damaged. Temperature will affect the frequency of pronunciation. He advocates making flutes of different specifications according to different temperatures, so they can't be mixed. He insisted that the flute must be scientific, and only with profound mathematical knowledge and operational ability can a standard flute be made.
