Here is the method I developed to compose an intricate corrente as part of a wider piano piece. First of all I chose a musical unit consisting of two superimposed pentachords (A and B).
The inversion of the harmonic intervals of this unit and of its inversion provided two further pentachords (C and D).
At this point it’s possible to arrange the four non-standard rows according to the preferred scheme. I followed an outline that I had projected in consideration of the requirement of an overall irregular rhythmic structure.
