Music is the arrangement of sound to create some combination of form, harmony, melody, rhythm, or otherwise expressive content. Music is generally agreed to be a cultural universal that is present in all human societies. Definitions of music vary widely in substance and approach. While scholars agree that music is defined by a small number of specific elements, there is no consensus as to what these necessary elements are. Music is often characterized as a highly versatile medium for expressing human creativity. Diverse activities are involved in the creation of music, and are often divided into categories of composition, improvisation, and performance. Music may be performed using a wide variety of musical instruments, including the human voice. It can also be composed, sequenced, or otherwise produced to be indirectly played mechanically or electronically, such as via a music box, barrel organ, or digital audio workstation software on a computer. Music often plays a key role in social events and religious ceremonies. The techniques of making music are often transmitted as part of a cultural tradition. Music is played in public and private contexts, highlighted at events such as festivals and concerts for various different types of ensembles. Music is used in the production of other media, such as in soundtracks to films, TV shows, operas, and video games. Listening to music is a common means of entertainment. The culture surrounding music extends into areas of academic study, journalism, philosophy, psychology, and therapy. The music industry includes songwriters, performers, sound engineers, producers, tour organizers, distributors of instruments, accessories, and publishers of sheet music and recordings. Technology facilitating the recording and reproduction of music has historically included sheet music, microphones, phonographs, and tape machines, with playback of digital music being a common use for MP3 players, CD players, and smartphones.

Anton Webern (German: [ˈantoːn ˈveːbɐn] ; 3 December 1883 – 15 September 1945) was an Austrian composer, conductor, and musicologist whose modernist music was among the most radical of its milieu in its lyrical, poetic concision and use of then novel atonal and twelve-tone techniques. His approach was typically rigorous, inspired by his studies of the Franco-Flemish School under Guido Adler and by Arnold Schoenberg's emphasis on structure in teaching composition from the music of Johann Sebastian Bach, the First Viennese School, and Johannes Brahms. Webern, Schoenberg, and their colleague Alban Berg were at the core of what became known as the Second Viennese School. Webern was arguably the first and certainly the last of the three to write music in an aphoristic and expressionist style, reflecting his instincts and the idiosyncrasy of his compositional process. Working from personal experience, he treated themes of love, nature, mysticism, and nostalgia. Unhappily peripatetic and often assigned light music or operetta in his early conducting career, he aspired to conduct what was seen as more respectable, serious music at home in Vienna. Following Schoenberg's guidance, Webern tried writing music of greater length during and after their World War I service, relying on the structural support of texts in many Lieder. He rose as a choirmaster and conductor, championing Gustav Mahler's music in Red Vienna and abroad. With Schoenberg based in Berlin, Webern began writing music of increasing confidence, independence, and scale using twelve-tone technique. Marginalized as a "cultural Bolshevist" in Fascist Austria and Nazi Germany, he maintained "the path to the new music", enjoyed international recognition, and relied more on teaching for income. He opposed fascist cultural positions but always espoused pan-Germanism and was torn, like friends and family, among uncertainties. His hope for moderate, stable, and successful governance of Austria within Nazi Germany proved misplaced, and he helped Jewish friends emigrate and hide while repeatedly considering emigrating himself. A soldier accidentally killed Webern after World War II. In a phenomenon known as post-Webernism, his music was celebrated by composers, musicians, and scholars. René Leibowitz, Pierre Boulez, Robert Craft, and Hans and Rosaleen Moldenhauer established it as an important part of modernism through performance, study, and advocacy. Igor Stravinsky assimilated it. To many, it represented a path to serialism. Broader understanding of Webern's expressive agenda, performance practice, and complex sociocultural and political context lagged. A historical edition of his music is underway.

Hilary Hahn (born November 27, 1979) is an American violinist. A three-time Grammy Award winner, she has performed throughout the world as a soloist with leading orchestras and conductors, and as a recitalist. She is an avid supporter of contemporary classical music, and several composers have written works for her, including concerti by Edgar Meyer and Jennifer Higdon, partitas by Antón García Abril, two serenades for violin and orchestra by Einojuhani Rautavaara, and a violin and piano sonata by Lera Auerbach.

Johannes Brahms (; German: [joˈhanəs ˈbʁaːms] ; 7 May 1833 – 3 April 1897) was a German composer, virtuoso pianist, and conductor of the mid-Romantic period. His music is noted for its rhythmic vitality and freer treatment of dissonance, often set within studied yet expressive contrapuntal textures. He adapted the traditional structures and techniques of a wide historical range of earlier composers. His œuvre includes four symphonies, four concertos, a Requiem, much chamber music, and hundreds of folk-song arrangements and Lieder, among other works for symphony orchestra, piano, organ, and choir. Born to a musical family in Hamburg, Brahms began composing and concertizing locally in his youth. He toured Central Europe as a pianist in his adulthood, premiering many of his own works and meeting Franz Liszt in Weimar. Brahms worked with Ede Reményi and Joseph Joachim, seeking Robert Schumann's approval through Joachim. He gained both Robert and Clara Schumann's support and guidance. Brahms stayed with Clara in Düsseldorf, becoming devoted to her amid Robert's insanity and institutionalization. The two remained close, lifelong friends after Robert's death. Brahms never married, perhaps in an effort to focus on his work as a musician and scholar. He was a self-conscious, sometimes severely self-critical composer. Though innovative, his music was considered relatively conservative within the polarized context of the War of the Romantics, an affair in which Brahms regretted his public involvement. His compositions were largely successful, attracting a growing circle of supporters, friends, and musicians. Eduard Hanslick celebrated them polemically as absolute music, and Hans von Bülow even cast Brahms as the successor of Johann Sebastian Bach and Ludwig van Beethoven, an idea Richard Wagner mocked. Settling in Vienna, Brahms conducted the Singakademie and Gesellschaft der Musikfreunde, programming the early and often "serious" music of his personal studies. He considered retiring from composition late in life but continued to write chamber music, especially for Richard Mühlfeld. Brahms's contributions and craftsmanship were admired by his contemporaries like Antonín Dvořák, whose music he enthusiastically supported, and a variety of later composers. Max Reger and Alexander Zemlinsky reconciled Brahms's and Wagner's often contrasted styles. So did Arnold Schoenberg, who emphasized Brahms's "progressive" side. He and Anton Webern were inspired by the intricate structural coherence of Brahms's music, including what Schoenberg termed its developing variation. It remains a staple of the concert repertoire, continuing to influence composers into the 21st century.

In music, the "Ode-to-Napoleon" hexachord (also magic hexachord, hexatonic collection, or hexatonic set class) is the hexachord named after its use in the twelve-tone piece Ode to Napoleon Buonaparte Op. 41 (1942) by Arnold Schoenberg (setting a text by Byron). Containing the pitch classes 014589 (C, D♭, E, F, G♯, A), it is given Forte number 6–20 in Allen Forte's taxonomic system. The primary form of the tone row used in the Ode allows the triads of G minor, E♭ minor, and B minor to easily appear. The "Ode-to-Napoleon" hexachord is the six-member set-class with the highest number of interval classes 3 and 4 yet lacks 2s and 6s. 6-20 maps onto itself under transposition three times (@0,4,8) and under inversion three times (@1,4,9) (six degrees of symmetry), allowing only four distinct forms, one form overlapping with another by way of an augmented triad or not at all, and two augmented triads exhaust the set as do six minor and major triads with roots along the augmented triad. Its only five-note subset is 5-21 (0,1,4,5,8), the complement of which is 7-21 (0,1,2,4,5,8,9), the only superset of 6-20. The only more redundant hexachord is 6-35. It is also Ernő Lendvai's "1:3 Model" scale and one of Milton Babbitt's six all-combinatorial hexachord "source sets". The hexachord has been used by composers including Bruno Maderna and Luigi Nono, such as in Nono's Variazioni canoniche sulla serie dell'op. 41 di Arnold Schönberg (1950), Webern's Concerto, Op. 24, Schoenberg's Suite, Op. 29 (1926), Babbitt's Composition for Twelve Instruments (1948) and Composition for Four Instruments (1948) third and fourth movements. The hexachord has also been used by Alexander Scriabin and Béla Bartók. It is used combinatorially in Schoenberg's Suite: P3: E♭ G F♯ B♭ D B // C A A♭ E F D♭ I8: G♯ E F D♭ A C // B D E♭ G F♯ B♭ Note that its complement is also 6-20.

The Austrian composer Arnold Schoenberg published four string quartets, distributed over his lifetime: String Quartet No. 1 in D minor, Opus 7 (1905), String Quartet No. 2 in F♯ minor, Op. 10 (1908), String Quartet No. 3, Op. 30 (1927), and the String Quartet No. 4, Op. 37 (1936). In addition to these, he wrote several other works for string quartet which were not published. The most notable was his early String Quartet in D major (1897). There was also a Presto in C major (c. 1895), a Scherzo in F major (1897), and later a Four-part Mirror Canon in A major (c. 1933). Finally, several string quartets exist in fragmentary form. These include String Quartet in F major (before 1897), String Quartet in D minor (1904), String Quartet in C major (after 1904), String Quartet Movement (1926), String Quartet (1926), String Quartet in C major (after 1927) and String Quartet No. 5 (1949). Schoenberg also wrote a Concerto for String Quartet and Orchestra in B♭ major (1933): a recomposition of a work by the Baroque composer George Frideric Handel.

The Wind Quintet, Op. 26, is a chamber music composition by Arnold Schoenberg, composed in 1923–24. It is one of the earliest of Schoenberg's compositions to use twelve-tone technique.

In music, a serenade (; also sometimes called a serenata, from the Italian) is a musical composition or performance delivered in honour of someone or something. Serenades are typically calm, light pieces of music. The term comes from the Italian word serenata, which itself derives from the Latin serenus. Sense influenced by Italian sera "evening", from Latin sera, fem. of serus "late".

A string trio is a group of three string instruments or a piece written for such a group. From at least the 19th century on, the term "string trio" with otherwise unspecified instrumentation normally refers to the combination violin, viola and cello. The classical string trio emerged during the mid-18th century and later expanded into four subgenres: the grand trio, the concertant trio, the brilliant trio, and the Hausmusik trio.

A septet is a formation containing exactly seven members. It is commonly associated with musical groups but can be applied to any situation where seven similar or related objects are considered a single unit, such as a seven-line stanza of poetry.

In music, variation is a formal technique where material is repeated in an altered form. The changes may involve melody, rhythm, harmony, counterpoint, timbre, orchestration or any combination of these. Variation is often contrasted with musical development, which is a slightly different means to the same end. Variation depends upon one type of presentation at a time, while development is carried out upon portions of material treated in many different presentations and combinations at a time.

Verklärte Nacht (Transfigured Night), Op. 4, is a string sextet in one movement composed by Arnold Schoenberg in 1899. Composed in just three weeks, it is considered his earliest important work. It was inspired by Richard Dehmel's poem of the same name and by Schoenberg's strong feelings upon meeting his future wife Mathilde Zemlinsky, who was the sister of his teacher, Alexander von Zemlinsky (1871–1942). Schoenberg and Zemlinsky married in 1901. The movement can be divided into five distinct sections which refer to the five stanzas of Dehmel's poem; however, there are no unified criteria regarding movement separation.
