     Part 3:    N e w   O r d e r

The retreat from tonality has not resulted in completely disordered structures, but in the new order: dodecaphony with the tonal series, where the classical patterns the chords, are replaced by the new patterns: permutational twelve-tone series. Isometric transformations of tonal music are replaced by permutational symmetries, where the invariant remains the twelve-tone material (mod 12) (Fig. 6: A Schoenberg - Wind quintet, op.26, where the basic series and their retrograde and retrograde inversion are visible only after the vertical reduction mod 12).

This way, the static symmetry of the classical tonal system is replaced by the dynamic permutational symmetry of a serial system: the classical symmetry is replaced by its generalization - colored (permutational) symmetry (Fig. 7).
