xenharmlib 0.3.0

A library for microtonal music theory

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.

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
