Caleidocicli” for instrumental group (1992), the first one, for 12
instruments, is harmonically built on the (0,1,2,6,8,10) chord and on its complementary one. The transposition
grades form a series of 11 figures (1,2,3,2,5,2,7,2,9,2,11); melodically,
each of the two chords develops one six-voice canon, of which the entries
are place along the axis of a rising six-tone scale.
second one, for two opposite quartets, is built harmonically upon the
alternation of two (0,2,6,9) dominant
seventh chords and of two chords of its (0,2,5,8) sensible seventh opposite,
which follow one after the other upon the transposition grades based on the
alternation of the (3-4-3-5) figures, corresponding to 4 sevenths of second
species placed at third minor distance. Each quartet develops the two chords so that the vertical
result corresponds to the octotonic tone-semitone chord.
third one, for 12 instruments, is built harmonically upon the (0,1,2,5,6,10)
chord and upon its (0,1,2,4,8,9)
complementary. The transposition grades form a series of 8 figures;
melodically each of the two chords develops one six-voice canon with unison
