Process music

My good friend and student Roberta shares with me a certain fascination with numerology – an occult study of number patterns (limited to their applicability in music, in my case). There is even a reproduction of a magic square (an arrangement of numbers where rows, columns and diagonals add up to the same sum – the “magic number”) on one of the walls in her house – the square that appears in Melancholia , an engraving by Albrecht Dürer.
