# Thirty years ago, Robby Kilgore invented a neat harmonization effect for Michael Brecker: http://robbykilgore.com/?p=19
# The basic idea is that incoming notes are doubled by rotating intervals. So you get diverse chords from the same melodic notes.
# This script is an attempt to reproduce the same effect.
