Several genres of music and description?

Several genres of modern music in the Yuelu version of the compulsory 3 history teaching, in the nineteenth lesson (music and fine arts) mentioned a few genres of modern music, but these terms are quite rusty for our history teachers, today specially organized for your reference. Neoclassical Music After the First World War, many experimental genres and trends emerged in Western music (such as Italian Futurism and Czech composer A. Haba's Differential Music), but on the other hand, some important composers went through a relatively stable process of stylistic development. New aesthetic concepts and musical thinking were emerging. From the early 1920s to the 1950s, neoclassicism was arguably the most influential musical genre.　Expressionism Expressionism and twelve-tone music The first genre of modern music, which followed closely on the heels of Impressionism and was very different from Impressionism in terms of aesthetics and compositional techniques, was Expressionism. Expressionism was a school of art that appeared in Germany before the First World War and became popular in Europe and the United States after the war. 1911, the Russian painter V. Kandinsky (1866-1944), who was active in Germany, together with the painters F. Malk (1880-1916) and A. Mack (1887-1914), founded the magazine "The Green Knight", which not only published the paintings of Kandinsky but also a number of works by Kandinsky and others. It not only published the paintings of Kandinsky and others, but also published many theories about expressionism in theater, painting and poetry, including the writings of the Austrian musician A. Schoenberg, thus launching the expressionist movement.　　The expressionism that originated in painting was directed against the objectivity of impressionism. They believed that art should neither "depict" nor "symbolize", but should directly express the spirit and experience of human beings, that is, art is not "depicting what is objectively seen before the eyes", but rather "subjectively expressing what is seen before the eyes". In other words, art does not "depict what we see objectively", but "subjectively expresses the gesture of the object in our eyes", that is to say, it expresses the author's spiritual world, the so-called inner spirit, which is combined with such morbid feelings as madness, despair, fear and anxiety, as well as with the "unimaginable destiny of mankind", and so on. and "the unimaginable fate of mankind".　　concrete music Music that is synthesized by recording all kinds of sounds (including musical sounds and noises) from nature and real life, and then processed by sound machines.　　It is a type of modernist music. It is characterized by expanding the concept of music to include all natural sounds. The earliest founder was the French engineer P. Scheufele, who in 1948 conducted experiments in the laboratory of Radio France Nationale, using noise, train sounds, human voices, percussion sounds and other materials. Scheufele processed the tapes of these sounds separately, played them at fast or slow speeds, rewound them, added echo reverb effects, cut them up, removed unwanted parts, and finally mixed them into new tapes to be broadcast as finished products. His early works include Railroad Etudes and Mexican Flute, and later Schaefer collaborated with P. Henry on Symphonies for One Person (see Modernist Music).　　After the emergence of concrete music, some people in France, the USA, Germany and Japan followed suit, including O. Messiaen, P. Blaise and Damien Lang. After the rise of electronic music, the characteristics of concrete music (i.e. the use of noise and natural sound in music) were absorbed by electronic music. The difference between the two is that concrete music uses natural sound, while electronic music directly uses electronic devices to produce the required sound, which makes it difficult to differentiate between the two in the sense of hearing. Opportunity music is a modern compositional method. Opportunity music maintains a connection with the original improvisation, but it has developed to extremes. Opportunistic music can be based on the arbitrary selection of musical material, or notation, which is then improvised by one or more players without any legal constraints. Such performances often result in unique features that can only be preserved by recording. Poetry recitations, stage movements, and even spontaneous audience participation can be added to the performance at will. It is also often accompanied by electronic and computer music. Stockhausen's Piano Piece No. 11, composed in 1956, is one of the masterpieces. It *** has nineteen fragments awarded on a sheet of paper, and the performer can play the part he sees at will. It also provides for six variations, and the player chooses a set of uses for each section, and after playing it three times, the piece is finished. The "Percussion Cycle" he composed in 1959 also has this feature. The player stands in the center of a circle of more than twenty percussion instruments, and plays either clockwise or counterclockwise. Sixteen sheets of music marked with special symbols are placed on the circle of instruments, and there is no fixed starting point or end point, so the player can start from any point and play the rest of the sheet music in sequence, and when the starting point is repeated after one cycle, the music will be finished. This kind of music is also represented by Keggie, Feldman, and Austin. Aleatoric Musi. also known as "Uncertainty Music". One of the genres of music. A type of Western modernist music. Represented by John Cage. Characterized by the pursuit of sound uncertainty (total or partial uncertainty), it allows the performer to improvise at will, producing a variety of musical sounds and noises, in order to seek to obtain accidental acoustic effects. The main works are "Imaginary Landscape No. 4" produced by Cage in 1951, "4 minutes and 33 seconds" (self-proclaimed "Piano Piece") produced in 1954, and "34 minutes and 26.776 seconds", a collaborative piano piece in the same year, as well as designing two processed pianos, with screws, erasers, wooden blocks and toys stuffed inside the strings, in order to pursue various kinds of sound effects. toys and other miscellaneous objects in pursuit of various special acoustic effects. There are many types of serendipitous music: there are works in which the pitch, beat, timbre, and intensity of the piece are determined by divination, rolling dice, or tossing coins, and there are works in which maps and horoscopes are used as the basis for composition. Electronic music Electronic mrsic(Eng) One of the modernist music genres. It refers to music that is "created" by the technical means of electronic computers (also called electronic synthesizers). It can be controlled and arranged according to the author, through a variety of complex electronic instruments, no theme or melody "free creation and play", processing into an electronic music works. It can also break down each tone into 1/4 to 1/12 tones, creating and playing a piece of music that cannot be played by ordinary instruments. It not only imitates various sounds in nature, but also creates various sound effects that are not found in nature. Nowadays, music played or accompanied by electronic instruments is also called "electronic music". Serialism One of the genres of Serialism. Serialism is one of the genres of serialism music. It emerged in the early 1950s. It is characterized by the use of mathematical principles and the combination of the two. It is characterized by the use of mathematical principles to record and arrange tones of different heights, lengths, strengths and tones in a sequential order, and to create music through computational methods, which is generally cumbersome, confusing and difficult to understand. Representative works include Wilbourn's Variations (Op. 27), Messiaen's piano piece "Types of Timbre and Intensity" and "Groups of Rhythmic Notes", and French composer Bouley's piece "Axe Without Master". There is also "sequence music" as "twelve-tone system music", and since the 1960s, it is often combined with electronic music.
