pctheory
pctheory is a Python library for using atonal music theory. It is useful for both computer-assisted composition in Python and analysis. Some of the many useful features include:
- Set-classes
- Generate all abstract subsets of a set-class
- Get Forte and Carter names for a set-class
- Work with microtonal sets
- Generate set-class-complexes
- Rows
- Generate a twelve-tone matrix
- Generate a rotational array
- Generate an invariance matrix
- Load a random all-interval, all-trichord, ten-trichord, or Babbit ten-trichord row
pctheory is much more specialized than music21, and offers substantially more functionality in atonal theory. Additionally, it does not use music21 objects, so there is less computational overhead when using pctheory. It is not difficult to create music21 objects from pctheory objects, which allows pctheory to be used along with music21.
Installation
pctheory is a Python package and can be installed with the command pip install pctheory from the terminal on your computer (Command Prompt or PowerShell on Windows, Terminal on Linux or macOS). Note that you need Python 3.10 or newer.
If the pip install command fails, you will need to build the wheel yourself. Create a virtual environment with the packages build, setuptools, and wheel installed. Then run the command python -m build from the root of this repository. The wheel will be found in the dist/ directory.
Quick start
There are three Jupyter notebooks in this repository that you can consult to get started with pctheory.
Stability
pctheory is currently in alpha status. This means that some functionality might not be stable yet. In particular, there isn't unit test coverage for the whole package at this point. However, the core functionality (such as pitch class operations, set-classes, and row functionality) does have test coverage and should be stable.
To see current testing coverage, you can take a look at the tests in the tests directory.
System Requirements
pctheory requires Python 3.10 or newer.
