The Petrushka chord is a recurring polytonal device used in Igor Stravinsky's ballet Petrushka and in later music. In the Petrushka chord, two major triads, C major and F major – a tritone apart – clash, "horribly with each other", when sounded together and create a dissonant chord. The six-note chord is contained within an octatonic scale.
