PyABC2

Python library for working with melodies in ABC notation.

This polar axis plot combines melody trajectory and note histogram. Each ring represents an octave (outer = higher). The trajectory changes color with progression through the tune (dark blue/purple to light yellow). Polar shows how the plot is generated, with the tune itself shown at the top.

Getting started

Install from PyPI:

pip install pyabc2

Then look at the example notebooks.
