Code for analyzing John Cage's Number Pieces.

See the following papers for more theoretical details:

The C code is provided as is, though it is quite dirty. It provides code for analyzing John Cage's Five⁵, Four², Four, and Three².

The Python code reads the output of the C program and builds the corresponding heatmaps and graphs.
