Dmitri Shostakovich in the context of "Lady Macbeth of the Mtsensk District (opera)"

A music school is an educational institution specialized in the study, training, and research of music. Such an institution can also be known as a school of music, music academy, music faculty, college of music, music department (of a larger institution), conservatory, conservatorium or conservatoire (/kənˈsɜːrvətwɑːr/ kən-SER-və-twar, French: [kɔ̃sɛʁvatwaʁ]). Instruction consists of training in the performance of musical instruments, singing, musical composition, conducting, musicianship, as well as academic and research fields such as musicology, music history and music theory.

Music instruction can be provided within the compulsory general education system, or within specialized children's music schools such as the Purcell School. Elementary-school children can access music instruction also in after-school institutions such as music academies or music schools. In Venezuela El Sistema of youth orchestras provides free after-school instrumental instruction through music schools called núcleos.

Alexander Konstantinovich Glazunov (10 August [O.S. 29 July] 1865 – 21 March 1936) was a Russian composer, music teacher, and conductor of the late Russian Romantic period. He was director of the Saint Petersburg Conservatory between 1905 and 1928 and was instrumental in the reorganization of the institute into the Petrograd Conservatory, then the Leningrad Conservatory, following the Bolshevik Revolution. He continued as head of the Conservatory until 1930, though he had left the Soviet Union in 1928 and did not return. The best-known student under his tenure during the early Soviet years was Dmitri Shostakovich.

Glazunov successfully reconciled nationalism and cosmopolitanism in Russian music. While he was the direct successor to Balakirev's nationalism, he tended more towards Borodin's epic grandeur while absorbing a number of other influences. These included Rimsky-Korsakov's orchestral virtuosity, Tchaikovsky's lyricism and Taneyev's contrapuntal skill. Younger composers such as Prokofiev and Shostakovich eventually considered his music old-fashioned, while also admitting he remained a composer with an imposing reputation, and a stabilizing influence in a time of transition and turmoil.

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.

Nikolai Semyonovich Leskov (Russian: Никола́й Семёнович Леско́в; 16 February [O.S. 4 February] 1831 – 5 March [O.S. 21 February] 1895) was a Russian novelist, short-story writer, playwright, and journalist, who also wrote under the pseudonym M. Stebnitsky. Praised for his unique writing style and innovative experiments in form, and held in high esteem by Leo Tolstoy, Anton Chekhov and Maxim Gorky among others, Leskov is credited with creating a comprehensive picture of contemporary Russian society using mostly short literary forms. His major works include Lady Macbeth of Mtsensk (1865), which was later made into an opera by Shostakovich); The Cathedral Folk (1872); The Enchanted Wanderer (1873); and "The Tale of Cross-eyed Lefty from Tula and the Steel Flea" (1881).

Leskov received his formal education at the Oryol Lyceum. In 1847 Leskov joined the Oryol criminal court office, later transferring to Kiev, where he worked as a clerk, attended university lectures, mixed with local people, and took part in various student circles. In 1857 Leskov quit his job as a clerk and went to work for the private trading company Scott & Wilkins owned by Alexander Scott, his aunt's Scottish husband.

A choral symphony is a musical composition for orchestra, choir, and sometimes solo vocalists that, in its internal workings and overall musical architecture, adheres broadly to symphonic musical form. The term "choral symphony" in this context was coined by Hector Berlioz when he described his Roméo et Juliette as such in his five-paragraph introduction to that work. The direct antecedent for the choral symphony is Ludwig van Beethoven's Ninth Symphony. Beethoven's Ninth incorporates part of the ode An die Freude ("Ode to Joy"), a poem by Friedrich Schiller, with text sung by soloists and chorus in the last movement. It is the first example of a major composer's use of the human voice on the same level as instruments in a symphony.

A few 19th-century composers, notably Felix Mendelssohn and Franz Liszt, followed Beethoven in producing choral symphonic works. Notable works in the genre were produced in the 20th century by Gustav Mahler, Igor Stravinsky, Ralph Vaughan Williams, Benjamin Britten and Dmitri Shostakovich, among others. The final years of the 20th century and the opening of the 21st century have seen several new works in this genre, among them compositions by Mikis Theodorakis, Peter Maxwell Davies, Tan Dun, Philip Glass, Hans Werner Henze, Krzysztof Penderecki, William Bolcom and Robert Strassburg.

The Fitzwilliam Quartet or Fitzwilliam String Quartet (FSQ) is a British string quartet founded in 1968 by four Cambridge undergraduates. The quartet is one of the longest-established chamber ensembles in the world and is particularly noted for its close association with the composer Dmitri Shostakovich, who entrusted them with the Western premières of his last three string quartets. The FSQ was the first group outside the Soviet Union to perform and record all fifteen of Shostakovich's string quartets, a cycle that earned them international acclaim and a long-term recording contract with Decca.

The quartet's Shostakovich recordings were highly decorated, winning the first-ever Gramophone Award for Chamber Music in 1977 and being included in Gramophone magazine's "100 Greatest-ever Recordings" in 2005. The composer himself held the quartet in high regard, reportedly telling Benjamin Britten that the Fitzwilliam were his "preferred performers of my quartets".

A violin concerto is a concerto for solo violin (occasionally, two or more violins) and instrumental ensemble (customarily orchestra). Such works have been written since the Baroque period, when the solo concerto form was first developed, up through the present day. Many major composers have contributed to the violin concerto repertoire.

Traditionally a three-movement work, the violin concerto has been structured in four movements by a number of modern composers, including Dmitri Shostakovich, Igor Stravinsky, and Alban Berg. In some violin concertos, especially from the Baroque and modern eras, the violin (or group of violins) is accompanied by a chamber ensemble rather than an orchestra—for instance, in Vivaldi's L'estro armonico, originally scored for four violins, two violas, cello, and continuo, and in Allan Pettersson's first concerto, for violin and string quartet.
