In “Rota” for 4 flutes (1991), the 43 possible 4-note chords are canonically developed, from the closest (0,1,2,3) to the widest (0,3,6,9) one, and viceversa, all amounting to 84 chords. The module is arranged on an all-interval ascending series of 12 figures, so that the module is repeated 7 times before being applied to the same chord. The initial situation comes again after 12x7=84 intervals, so that the 84 supplementary chords are applied to a 84-figure module. The entries of the deriving canon are placed on augmented forth at 14 ¾ -bar  distance.
