Petrushka (Russian: Петрушка) is a stock character of Russian folk puppetry (rayok) known at least since 17th century. Petrushkas were used as marionettes, as well as hand puppets. Traditionally he was a kind of a jester distinguished by red dress, red kolpak, and often a long nose.

Although the Russian word "petrushka" has a homonym meaning "parsley," in this context the word is actually a hypocoristic for "Pyotr" (Пётр), which is Peter in Russian. However, the character has little or nothing in common with such stock characters as Petruccio or Pierrot. Petrushka is rather a Russian Punch or Pulcinella in character.

It was the Empress Anna Ioannovna’s court jester Pietro-Mira Pedrillo from Italy, who served as a prototype for Petrushka.

Petrushka’s voice was created with the help of a special whistle, and the dialogue was based on a momentary change of the pishchik and the “live” voice of other characters. There were a number of basic plots: the medical treatment of Petrushka, his learning of soldier’s service, the scene with his bride, the buying of a horse and testing it.

Igor Fyodorovich Stravinsky (sometimes spelled Strawinsky or Stravinskii; Russian: Игорь Фёдорович Стравинский, transliterated: Igorʹ Fëdorovič Stravinskij; Russian pronunciation: [ˌiɡərʲ ˌfʲjodɐrɐvʲɪtɕ strɐˈvʲinskʲɪj]; 17 June [O.S. 5 June] 1882 – 6 April 1971) was a Russian, and later French and American composer, pianist and conductor. He is acknowledged by many as one of the most important and influential composers of the 20th century.

Stravinsky's compositional career was notable for its stylistic diversity. He first achieved international fame with three ballets commissioned by the impresario Sergei Diaghilev and first performed in Paris by Diaghilev's Ballets Russes: The Firebird (1910), Petrushka (1911) and The Rite of Spring (1913). The Rite of Spring, which provoked a riot during its premiere, transformed the way in which subsequent composers thought about rhythmic structure and was largely responsible for Stravinsky's enduring reputation as a musical revolutionary who pushed the boundaries of musical design. His so-called Russian phase was followed in the 1920s by a period in which he turned to neoclassical music. The works from this period tended to make use of traditional musical forms (concerto grosso, fugue and symphony). They frequently concealed a vein of intense emotion beneath a surface appearance of detachment or austerity and often paid tribute to the music of earlier masters, for example J.S. Bach and Tchaikovsky. In the 1950s, Stravinsky adopted serial procedures. His compositions of this period shared traits with examples of his earlier output: rhythmic energy, the construction of extended melodic ideas out of a few two- or three-note cells and clarity of form, of instrumentation and of utterance.
