This is a list of compositions by composer Alfred Schnittke.

Alfred Garrievich Schnittke (24 November 1934 – 3 August 1998) was a Soviet and Russian composer. Among the most performed and recorded composers of late 20th-century classical music, he is described by musicologist Ivan Moody as a "composer who was concerned in his music to depict the moral and spiritual struggles of contemporary man in [...] depth and detail." Schnittke's early music shows the strong influence of Dmitri Shostakovich. He developed a polystylistic technique in works such as the epic Symphony No. 1 (1969–1972) and his first concerto grosso (1977). In the 1980s, Schnittke's music began to become more widely known abroad with the publication of his second (1980) and third (1983) string quartets and the String Trio (1985); the ballet Peer Gynt (1985–1987); the third (1981), fourth (1984), and fifth (1988) symphonies; and the viola concerto (1985) and first cello concerto (1985–1986). As his health deteriorated, Schnittke's music started to abandon much of the extroversion of his polystylism and retreated into a more withdrawn, bleak style.

On Guard for Peace (Russian: На страже мира, romanized: Na strazhe mira), also translated as On Guard of Peace, Op. 124 is an oratorio by Sergei Prokofiev scored for narrators, mezzo-soprano, boy soprano, boys choir, mixed choir, and symphony orchestra. Each of its ten movements sets texts by Samuil Marshak, who had collaborated previously with the composer in the work Winter Bonfire, Op. 122. Prokofiev composed On Guard for Peace under difficult personal circumstances. He had been among six composers censured by the Union of Soviet Composers in its 1948 Anti-Formalist Resolution on Music, which had immediate professional and financial consequences for him. The resulting stress exacerbated his chronic health problems from hypertension, which led to a stroke in 1949. Against his doctors' advice, Prokofiev wanted to compose a large oratorio on the theme of world peace, which he hoped would result in a paid commission from the Union of Soviet Composers or the Committee on Arts Affairs. With help from Alexander Fadeyev and Sergey Balasanian, Prokofiev was granted a commission for his oratorio from the children's programming division of the Radio Information Committee. During the composition process, Prokofiev revised the name of the oratorio and some of its movements several times before settling on their final names. As in many of his late works, Prokofiev willingly amended his score according to the advice offered by his collaborators and friends. On Guard for Peace was premiered on December 19, 1950, in Moscow; the performance was conducted by Samuil Samosud. It was received warmly in the Soviet Union, where it earned a Stalin Prize, second class, Prokofiev's last; it also signaled the beginning of his political rehabilitation. Discourse about the work in the West was affected by the Cold War and tended to be hostile. Its reputation there has remained mixed.
