# Xenharmlib
Xenharmlib is a generalized music theory library that supports traditional
Western and non-western harmonic systems, unconventional microtonal and
macrotonal tunings, diatonic and posttonal set theory and non-standard
notations.
[Click here for the official documentation](https://xenharmlib.readthedocs.io/en/latest/)
## Features
A selection of things supported by xenharmlib:
* Equal division tunings (e.g. Western, Modern Arabic, Turkish Makam,
Bohlen-Pierce, Wendy Carlos' Gamma Scale)
* Western notation (including interval naming)
* Up/Down notation (a superset of Western notation)
* Analysis of intervals, scales, and their relations to one another
* Group theoretical analysis (integer pitches, pitch classes, etc)
* Interval sequence pattern matching
* Modulation suggestions for arbitrary key changes
* Basic posttonal analysis (normal & prime form calculations, inversion, etc)
## Roadmap
A list of planned features (not necessarily in chronological order):
* Templates for Western music
* Plugin interface for score rendering backends
* Advanced posttonal analysis (interval vectors, z-Relations, Forte numbers)
* Rothenberg propriety and interval matrices
* MOS scale generation utilities
* Just Intonation and prime limit tunings
* Extended Helmholtz-Ellis JI Pitch Notation
* Odd Limit Tunings
* Arel-Ezgi-Uzdilek notation
