# New on CTAN: helmholtz-ellis-ji-notation

The helmholtz-ellis-ji-notation package is a simple LaTeX implementation of HEJI2 that allows for in-line typesetting of microtonal accidentals for use within theoretical texts, program notes, symbols legends, etc.

The package’s Catalogue entry can be viewed at https://ctan.org/pkg/helmholtz-ellis-ji-notation The package’s files themselves can be inspected at http://mirror.ctan.org/fonts/helmholtz-ellis-ji-notation/

## helmholtz-ellis-ji-notation – Beautiful in-line microtonal just intonation accidentals

The Helmholtz-Ellis JI Pitch Notation (HEJI), devised
in the early 2000s by Marc Sabat and Wolfgang von Schweinitz,
explicitly notates the raising and lowering of the
*untempered* diatonic Pythagorean notes
by specific microtonal ratios defined for each prime.
It provides visually distinctive “logos” distinguishing
families of justly tuned intervals that relate to the
harmonic series.
These take the form of strings of additional accidental symbols
based on historical precedents,
extending the traditional sharps and flats.
Since its 2020 update, HEJI ver. 2 (“HEJI2”) provides unique
microtonal symbols through the 47-limit.

This package is a simple LaTeX implementation of HEJI2 that allows for in-line typesetting of microtonal accidentals for use within theoretical texts, program notes, symbol legends, etc.

Documents must be compiled using XeLaTeX.
