We have considered here two complementary pentatonic
scales: A minor (all on the white keys) and G flat
major (on the black keys), obtaining the following
decaphonic series: A, C, D, E, G flat, G, A flat, B
flat, D flat, E flat. The numbers from 0 to 9 were then
associated with the notes: each measure of the
composition translates thereby a natural integer, from
1 to 100.
