ENTRA



 

 

 


In “Nuovi 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.



The 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.



The 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 entries.
