Schönberg sought "unity and regularity" in music, which had to be achieved without tone procedures, because Schoenberg believed that tone had run its course. For fifteen years, he followed a path which led him to the “discovery” of the “method of composition with twelve tones which only relate to each other”. Schoenberg experimented with serializing small groups of notes before applying the idea to all twelve. Schoenberg's first compositions in the new twelve-tone idiom were published in the Piano Suite. Opus. 25 between 1921 and 1923, each of the six pieces of which is twelve-tone. (12 note system). Sonically, he abandoned traditional tonality and harmony as well as other long-established musical languages, so that the sound and tone of the music created a great disparity, resulting in a particular sound color, twisted textures, complex rhythmic counterpoint and delicate timbre changes. This work proclaims to the world that Schoenberg created a new system and technology for the composer and set a new milestone in the history of music. As Canadian pianist Glenn Gould assessed: “In the first quarter of this century, I dare say, no work for solo piano can compare with it. » First of all, we must have some knowledge of the 12 tones. In an octave, the interrelation of the twelve chromatic tones is equally important. The traditional major and minor scales are completely abandoned by Schoenberg. Second, these twelve notes can be arranged in any order in a sequence, but cannot reproduce the phenomenon. However, this is a very complex and strict principle. At the same time, the principle of sound also conforms to the above arrangement, therefore, the traditional "triad" ...... middle of paper ...... is parallel to a triple movement barely perceptible in the "Mnuett". Conversely, while an antecedent-consequent phraseology is clearly audible at the beginning of the "Musette", the tonal implications of the title, mentioned above, are addressed and modified. After all, one could say that the 12-tone system is anti-musical because it supplants the centuries-old development of harmony and vocal direction with a new harmonic "language." Due to its special artistic characteristics, depicting the "fusion of old and new", Schoenberg merges traditional and modern elements into one, allowing twelve-tone works to have vitality and expressiveness. Arnold Schoenberg said: “People accuse me of being a mathematician. , but I am not a mathematician, I am a geometer.” He decided to use his knowledge of the rules to break them, and he broke them..
