Jird is a little language for writing and hearing music in just intonation.

It uses ratios to express frequencies, durations, and volumes.

The jird documentation is available on readthedocs.

Common dev tasks are wrapped with tox. With tox installed, running tox in the jird repo runs all the non-slow tests and various checks on the code and docs. See the tox.ini file for the individual tasks, which can be run as tox -e typeguard for example.
