Twelve-tone technique music is completely different from impressionism in aesthetic thought and creative technique. They believe that art should not be "described" or "symbolized", but should directly express human spirit and experience. This view comes down in one continuous line with expressionism in painting, that is, revealing the spiritual world of human beings through art, and confusing morbid emotions such as madness, despair, fear and anxiety with the incredible fate of human beings.
This technique is absolutely unconventional in composition techniques, completely ignoring the tonality law and harmony function law in the past, but giving equal attention to the twelve tones in octave, abandoning the concepts of tonic, tonic and subordinate sounds in the past, making atonality occupy an absolute dominant position. Because the old melody track is destroyed, the melody is neither balanced nor repeated, just a series of unique sounds. The rhythm is also elusive, almost no rhythm, breaking the previous balance, so it is very free. In the arrangement and orchestration of the band, we no longer pursue the huge and exaggerated sound in the past, but adopt a delicate and simple small arrangement with obvious chamber music attributes, but the color is not as leisurely and indifferent as Impressionism, but simple and lively, strong and powerful.
The first composer who tried twelve-tone technique was generally the Austrian composer Haue. After years of exploration by Austrian composer Schoenberg, a musical expressionist, and his disciples Berger and Weber, they all proved the possibility of this new thinking in music creation with their own practice. The basic technique of their composition is that all twelve semitones form a musical sequence in a fixed order, and each tone in the musical sequence cannot be repeated. It has no concept of theme, but a skeleton, a musical concept that permeates the works that use it. 1923, Schoenberg's five piano pieces and chamber music serenade; Berg's violin concerto and operetta Lulu; Weber's Variations on the Piano (Op.27) and Six Short Songs (Op.9) are their representative works.
