I watch Bach in a graphic manner as the music is highlighted in color as it moves along.
I realized that Toccata and Fugue was like a fractal with an added dimension of pitch and frequency. An audio fractal may only be doubled in rhythm and added in its simplest form an octave higher.
Add counterpoint lines and the fractal creates yet another dimension.
This would be a different approach to machine learned chorale 4 voice leading Bach. The usual method is by programing examples in the hundreds and have the computer create a new version based on those examples.
