China traditional music has experienced some new developments in modern times. With the modernization of China society, traditional music has also been influenced by western music, and began to communicate and integrate with western music.

For example, in the performance of traditional musical instruments such as pipa and erhu, new playing skills and forms are introduced, which improves the expressive force and appeal of these instruments. In addition, traditional music has also tried to integrate with western music elements, resulting in new music forms, such as "new folk music" that integrates Chinese and western music.

Secondly, traditional music has also begun to try to combine with western music elements in its creation. For example, at the beginning of the 20th century, musicians in China began to draw lessons from the harmony and melody of western music to create modern symphonies and chamber music with China characteristics. These works not only retain the characteristics of China's traditional music, but also incorporate the elements of western music, opening up a new road for the development of China's music.

In addition, China traditional music has made new progress in the field of education. With the gradual popularization and improvement of music education in China, traditional music has gradually entered schools and educational institutions and become one of the important contents for students to learn music. This not only makes the traditional music get better inheritance and protection, but also provides strong support for the diversified development of China music.

In a word, the new development of modern traditional music in China is diversified, including the improvement and innovation of performance forms, the combination of Chinese and western music in creation, and the new development in the field of education. These new developments not only provide new opportunities and challenges for the inheritance and development of China's traditional music, but also provide strong support and promotion for the diversified development of China's music.
