The representative composer of the accidental music school is Berg.

Alban Berg (1885-1935), a disciple of Schoenberg, founded the "New Viennese School" with Schoenberg and Webern, and was a representative figure of Expressionist music. His exploration of composition techniques brought a revolution to music throughout the 20th century.

Beginning in 1904, Berg studied with Schoenberg. Before that, he had almost no formal music training. After four years of study, he wrote Opus No. 1, a single-movement "Piano Sonata". Although the work's bleak tones and melancholy style of late Romanticism are partly influenced by Schoenberg and Mahler, the work's rich material and supreme confidence are undoubtedly the work of a master.

The 1910 "String Quartet" was the last work created by Berg under Schoenberg. Afterwards, Berg completely abandoned the tonal principle that a work must have one main key. In 1911 he married Helene Nahowski, and the music of this period was influenced by their love.

Berg’s life:

Berg lived in Vienna all his life. He was born into a declining aristocratic family. Berg served in the Austrian army from 1915 to 1917, and from 1917 to 1920 he composed his masterpiece, the opera Wozzeck (based on the play by Georg Büchner). Although the sound is extremely complex, his sympathetic and human portrayal of the soldier Wozzeck, the intense dramatic tension is almost unbearable, deeply affecting the audience.

In 1925, Berg completed the "Chamber Concerto" for piano, violin and 13 woodwind instruments. In 1935, Berg was commissioned to compose the "Violin Concerto" to commemorate Mahler's widow Alma and architecture. Manon, daughter of Walter Gropius.

Berger also wrote Bach's hymn "Es ist genug" (Es ist genug) into the final movement to form a moving elegy, and the work was quickly completed. But he would never hear his own work performed again: in December 1935, Berg died of sepsis, and the "Violin Concerto" became his requiem. Berg's important works also include "Lulu", "Lyric Suite", etc.
