Introduction

Welcome to the documentation for the Python package gmgcode, a project aimed at providing useful tools in the context of music theory and pitch-set theory.

This framework facilitates the computation of numerous properties of a pitch-class set, including a convenient PCSet class, explorative tools, and analysis of pitch-class set symmetry under group action.

This documentation is part of a larger guide on music theory. If you have not already, be sure to check out Greg’s Musical Guides.

Dependencies

• matplotlib ≥ 3.3.3
• networkx ≥ 2.8
• numpy ≥ 1.22.3

These may be installed easily by running the following command in the parent directory where gmgcode is installed: pip install -r gmgcode/requirements.txt.

PCSet

Housed in gmgcode.pcs_object, the PCSet object class is the primary component of gmgcode. This class embodies a pitch-class set, centralizing set operations, transformations, and property computation.

Methods

PCSet provides a myriad of methods for computing pitch set transformations, and intervallic and geometric properties.
