xenharmlib 0.1.1

A library for microtonal music theory

Xenharmlib

Xenharmlib is a music theory library for the exploration and research of microtonality, diatonic set theory, non-standard notations, and many more. The library implements a superset of Western classical music theory, so you can also use it to compose and analyze music in the boundaries of the common practice period or 20th century Western music.

So far it supports the following:

• Equal division tunings (e.g. Western, Modern Arabic, Bohlen-Pierce)
• Analysis of intervals, scales, and their relations to one another
• Group theoretical analysis (integer pitches, pitch classes, etc)
• Up/Down Notation (a superset of Western accidental notation)
• Building blocks for custom notations

Coming soon:

• Maximally even sets
• Interval vectors and related properties
• Key signature support for Up/Down Notation scales
• Scale and triad generators
• Just Intonation and Prime Limit Tunings
• Odd Limit Tunings
• Extended Helmholtz-Ellis JI Pitch Notation
