The helmholtz-ellis-ji-notation package

for typesetting beautiful in-line microtonal just intonation accidentals

(v1.1 – 2020-05-19)

Overview

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.

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, symbol legends, etc.

The documentation may be found in helmholtz-ellis-ji-notation.pdf.

Installation

First, install the HEJI2Text.otf font file (available in .zip folder or from under JI RESOURCES at plainsound.org).

Then to install the LaTeX package, use one of the following methods:

• Use the package manager of your TeX system
  • TeXLive: tlmgr install helmholtz-ellis-ji-notation
  • MiKTeX: search for helmholtz-ellis-ji-notation in the MiKTeX Package Manager

• Get the source (helmholtz-ellis-ji-notation.zip) from CTAN and extract it, run latex on helmholtz-ellis-ji-notation.ins to generate the package and configuration files, and move all generated files into a directory where LaTeX will find them, e.g., MiKTeX X.X/tex/latex/helmholtz-ellis-ji-notation/.
