This is a library of functions for working with regular temperament theory, implemented in Wolfram Language. It was developed by Dave Keenan and Douglas Blumeyer mostly from 2021 - 2022.

The code is maintained and shared on GitHub here: https://github.com/cmloegcmluin/RTT

More details can be found on the README there.

Temperament exploration

The functions implemented include:


Puts the given mapping into canonical form (i.e. defactored Hermite form): it defactors it and puts it into HNF.

mapMerge[t1, t2...]
commaMerge[t1, t2…]

Per Temperament merging.


For a mapping, returns the canonical form of the basis for its nullspace. For a comma basis, vice-versa: returns the canonical form of its mapping.

Temperament addition

sum[t1, t2]
diff[t1, t2]

Per Temperament addition.

Nonstandard domains

changeBasis[t, targetBasis]

Per Doman basis#Changing domain basis.


If you are interested in exterior algebra, this library also includes modules with helpful functions.
