Second Viennese School in the context of "Anton Webern"

Theodor W. Adorno (/əˈdɔːrnoʊ/ ə-DOR-noh; German: [ˈteːodoːɐ̯ aˈdɔʁno] ; born Theodor Ludwig Wiesengrund; 11 September 1903 – 6 August 1969) was a German philosopher, musicologist, and social theorist. He was a leading member of the Frankfurt School of critical theory, whose work has come to be associated with thinkers such as Ernst Bloch, Walter Benjamin, Max Horkheimer, Erich Fromm, and Herbert Marcuse, for whom the works of Sigmund Freud, Karl Marx, and G. W. F. Hegel were essential to a critique of modern society. As a critic of both fascism and what he called the culture industry, his writings—such as Dialectic of Enlightenment (1947), Minima Moralia (1951), and Negative Dialectics (1966)—strongly influenced the European New Left.

In an intellectual climate shaped by existentialism and logical positivism, Adorno developed a dialectical conception of history and philosophy that challenged the foundations of both, anticipating the divide that would later emerge between the analytic and continental traditions. As a classically trained musician, Adorno studied composition with Alban Berg of the Second Viennese School, influenced by his early admiration for the music of Arnold Schoenberg. Adorno's commitment to avant-garde music formed the backdrop of his subsequent writings and led to his collaboration with Thomas Mann on the latter's novel Doctor Faustus (1947), while the two men lived in California as exiles during the Second World War. Working at the newly relocated Institute for Social Research, Adorno collaborated on influential studies of authoritarianism, antisemitism, and propaganda that would later serve as models for sociological studies the institute carried out in post-war Germany.

Atonality in its broadest sense is music that lacks a tonal center, or key. Atonality, in this sense, usually describes compositions written from about the early 20th century to the present day, where a hierarchy of harmonies focusing on a single, central triad is not used, and the notes of the chromatic scale function independently of one another. More narrowly, the term atonality describes music that does not conform to the system of tonal hierarchies that characterized European classical music between the seventeenth and nineteenth centuries. "The repertory of atonal music is characterized by the occurrence of pitches in novel combinations, as well as by the occurrence of familiar pitch combinations in unfamiliar environments".

The term is also occasionally used to describe music that is neither tonal nor serial, especially the pre-twelve-tone music of the Second Viennese School, principally Alban Berg, Arnold Schoenberg, and Anton Webern. However, "as a categorical label, 'atonal' generally means only that the piece is in the Western tradition and is not 'tonal'", although there are longer periods, e.g., medieval, renaissance, and modern modal music to which this definition does not apply. "Serialism arose partly as a means of organizing more coherently the relations used in the pre-serial 'free atonal' music. ... Thus, many useful and crucial insights about even strictly serial music depend only on such basic atonal theory".

The twelve-tone technique—also known as dodecaphony, twelve-tone serialism, and (in British usage) twelve-note composition—is a method of musical composition. The technique is a means of ensuring that all 12 notes of the chromatic scale are sounded equally often in a piece of music while preventing the emphasis of any one note through the use of tone rows, orderings of the 12 pitch classes. All 12 notes are thus given more or less equal importance, and the music avoids being in a key.

The technique was first devised by Austrian composer Josef Matthias Hauer, who published his "law of the twelve tones" in 1919. In 1923, Arnold Schoenberg (1874–1951) developed his own, better-known version of 12-tone technique, which became associated with the "Second Viennese School" composers, who were the primary users of the technique in the first decades of its existence. Over time, the technique increased greatly in popularity and eventually became widely influential on mid-20th-century composers. Many important composers who had originally not subscribed to or actively opposed the technique, such as Aaron Copland and Igor Stravinsky, eventually adopted it in their music.

Alban Maria Johannes Berg (/bɛərɡ/ BAIRG; Austrian German: [ˈalbaːn ˈbɛrg]; 9 February 1885 – 24 December 1935) was an Austrian composer of the Second Viennese School. His compositional style combined Romantic lyricism with the twelve-tone technique. Although he left a relatively small oeuvre, he is remembered as one of the most important composers of the 20th century for his expressive style encompassing "entire worlds of emotion and structure".

Berg was born and lived in Vienna. He began to compose at the age of fifteen. He studied counterpoint, music theory and harmony with Arnold Schoenberg between 1904 and 1911, and adopted his principles of developing variation and the twelve-tone technique. Berg's major works include the operas Wozzeck (1924) and Lulu (1935, finished posthumously), the chamber pieces Lyric Suite and Chamber Concerto, as well as a Violin Concerto. He also composed a number of songs (lieder). He is said to have brought more "human values" to the twelve-tone system; his works are seen as more "emotional" than those of Schoenberg. His music had a surface glamour that won him admirers when Schoenberg himself had few.

Arnold Schoenberg or Schönberg (13 September 1874 – 13 July 1951) was an Austrian and American composer, music theorist, teacher and writer. He was among the first modernists who transformed the practice of harmony in 20th-century classical music, and a central element of his music was its use of motives as a means of coherence. He propounded concepts like developing variation, the emancipation of the dissonance, and the "unity of musical space".

Schoenberg's early works, like Verklärte Nacht (1899), represented a Brahmsian–Wagnerian synthesis on which he built. Mentoring Anton Webern and Alban Berg, he became the central figure of the Second Viennese School. They consorted with visual artists, published in Der Blaue Reiter, and wrote atonal, expressionist music, attracting fame and stirring debate. In his String Quartet No. 2 (1907–1908), Erwartung (1909), and Pierrot lunaire (1912), Schoenberg visited extremes of emotion; in self-portraits he emphasized his intense gaze. While working on Die Jakobsleiter (from 1914) and Moses und Aron (from 1923), Schoenberg confronted popular antisemitism by returning to Judaism and substantially developed his twelve-tone technique. He systematically interrelated all notes of the chromatic scale in his twelve-tone music, often exploiting combinatorial hexachords and sometimes admitting tonal elements.

The term string quartet is a type of musical composition or a group of four people who play them. Many composers from the mid-18th century onwards wrote string quartets. The associated musical ensemble consists of two violinists, a violist, and a cellist.

The string quartet was developed into its present form by the Austrian composer Joseph Haydn, whose works in the 1750s established the ensemble as a group of four more-or-less equal partners. Since that time, the string quartet has been considered a prestigious form; writing for four instruments with broadly similar characteristics both constrains and tests a composer. String quartet composition flourished in the Classical era, and Mozart, Beethoven and Schubert each wrote a number of them. Many Romantic and early-twentieth-century composers composed string quartets, including Mendelssohn, Schumann, Brahms, Dvořák, Janáček, and Debussy. There was a slight lull in string quartet composition later in the 19th century, but it received a resurgence in the 20th century, with the Second Viennese School, Bartók, Shostakovich, Babbitt, and Carter producing highly regarded examples of the genre, and it remains an important and refined musical form.
