In “Riflessi lunari” (1990), for double wind quintet, a (0,2,5,7,9) pentatonic harmonic field  is developed canonically by a wind quintet; its opposite is given to another wind quintet. The transposition grades of “Riflessi lunari” follow a permuting series of 30 figures  which  is divided into five six-member parts: 1-4-3-2-5-6; 1-2-6-3-4-5; 3-1-5-4-6-2; 3-5-1-6-4-2; 1-3-6-5-2-4. Hence derives a four-voice canon, of which the entries are placed at five 6/8-measure intervals , revolving around a  descending diminuted seventh axis (d,h,gis,f). The fifth voice develops freely and the five voices complete vertically the pentatonic sound field. The whole piece develops at the same time at its opposite, so that there derives another canon, opposite the first one, of which the entries are placed along a rising diminuted seventh axis (g,b,cis,e). The piece is divided into three parts. In the first part the first canon develops, and  then the second one (opposite); in the second part the first canon develops at the same time as the second one; in the third part at first the opposite appears and then the original one again.
