More precisely, the complexe sonore is Igor Stravinsky's use of diatonic and whole tone motifs, and scales, against an octatonic background, rotated by minor thirds. Stravinsky, "considered them to be in a perpetual state of potential symmetrical rotation by minor thirds (hereafter represented by the figures /0 3 6 9/) under which the octatonic background scale is invariant."
