In “Fughetta a 6 su un solo accordo”, for strings
(1986), the (0,2,4,6,9,10) chord develops vertically, so as to create
horizontal canon lines. The transposition grades, upon which the “Fughetta”
chord revolves, form a series of 10 figures: 3-2-3-4-3-6-3-8-3-10: the deriving
canon is six-voiced, where entries are placed along the axis of a descending
diminished seventh (es, c, a, fis). The piece is divided in two parts:
in the second part the transposition grades are inverted, so as to develop
another canon along the axis of a rising diminished seventh (g,b,cis,e).
