Another seminal chord is by the composer, Igor Stravinsky. Actually, there are two made famous by him. One is the "Petrouchka" chord, which consists of a combination of a C-major chord and an F#-major chord. Those two have no pitches in common and are located a tritone (augmented 4th) apart. The notes in ascending order are C-C#-E-F#-G-A#. The net effect, however, resembles a whole tone scale. The other chord is the "Rite of Spring" chord, which consists of a combination of an E-major-minor seventh (E7) chord and an Eb-major-minor seventh (Eb7) chord. Again, these two chords have no common tones, so the effect is almost like a noisy percussive chord.
