Abstract: Webern was one of the most representative composers of twelve-tone serial music, and was also the most loyal follower of this technique. In his twelve-tone serial music creation, he showed his own style characteristics. By using the general statement method in music history, this paper briefly summarizes the formation and development of twelve-tone serial music in the first half of the 20th century from a macro perspective, and at the same time, reviews Webern's twelve-tone serial music creation. Then, the paper analyzes many of his works from four aspects of pitch, rhythm, counterpoint and texture, summarizes the main technical features in his works, and explores the close relationship between Webern and the development of twelve-tone serial music. The research aims to promote the study of Webern and twelve-tone serial music.
