Petrushka chord
The Petrushka chord is a recurring polytonal device used in Igor Stravinsky's ballet Petrushka and in later music. These two major triads, C major and F♯ major – a tritone apart – clash, "horribly with each other", when sounded together and create a dissonant chord.[1]
Petrushka and origin[edit]
Although attributed to Stravinsky, the chord (or, more precisely, two simultaneous major chords set a tritone apart, specifically F and B major) was present much earlier in Franz Liszt's Malédiction Concerto.[7] (Although the exact date of the composition remains unknown, it is estimated by Humphrey Searle to be from about 1840; the composition is believed to have originated from one of Liszt's early works, performed in 1827.[8])
Maurice Ravel uses this chord in his piano work Jeux d'eau to create flourishing, water-like sounds that characterize the piece. In his article "Ravel's 'Russian' Period: Octatonicism in His Early Works, 1893-1908", Steven Baur notes that Jeux d'eau was composed in 1901, ten years before Stravinsky composed Petrushka (1911), suggesting that Stravinsky may have learned the trick from Ravel. Stravinsky heard Jeux d'eau and several other works by Ravel no later than 1907 at the "Evenings for Contemporary Music" program.[9]
Stravinsky used the chord repeatedly throughout the ballet Petrushka to represent the puppet and devised the chord to represent the puppet's mocking of the crowd at the Shrovetide Fair.[10] Eric Walter White suggests and dismisses the possibility that the Petrushka chord is derived from Messiaen's "second Modes of limited transposition" (the octatonic scale) in favor of a "black key/white key bitonality" which results from, "Stravinsky's well known habit of composing at the piano."[11]
Other uses[edit]
The 1979 song "Kogaion" by Romanian progressive rock band Sfinx makes use of the chord.
The Petrushka chord is dominantly used in the track Above the Clouds, from the 2003 simulation game Sim City 4.
