CONTORNI was composed in 1978.
The title means 'outlines' or 'contours' in Italian and the word is here used about musical figures.
The contours can be drawn in two ways. A short, strong tone is given reverberation by the weak, long tone of another instrument. Melodic figures is given a few accents, so the figures get an outline.
Also, in other respects CONTORNI is thorough sonic and aleatoric and the work suggests the second movement of my piano concerto.
