Octatonic scale on E (bottom), and symmetrical rotations by minor third (t3) of the Dorian mode
on E, G, B♭
, and D♭
, (top three) from that scale.
The complexe sonore is an octatonic chord consisting of minor third relations.
More precisely, the complexe sonore is Igor Stravinsky's use of diatonic and whole tone motifs, and scales, against a 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."
