Code by Graham Breed, forked from https://bitbucket.org/x31eq/microlily.
This package adds support for microtonal notation in Lilypond, including Sagittal and Extended Helmholtz-Ellis notations.
The Sagittal font and musical examples were provided by Dave Keenan and George Secor. There's some kind of license on them.
The HE font for Extended Helmholtz-Ellis Pitch Notation is shareware by Marc Sabat and can be download here. The HE font should be installed as a system font.
This package includes the Sagittal font. More information at http://sagittal.org.
Install using lyp
lyp install microlily\require "microlily"
...(For actual examples look at the test directory)
(Yes, as far as documentation goes this README kinda sucks. Pull requests are welcome!)
\athenian - support for just intonation with Athenian EDA accidentals.
\he - Extended Helmholtz-Ellis JI Pitch Notation support.
\"ji12" - just intonation written as 12 note equal temperament (this makes sense when used with cents).
\promethean - more precise accidentals than Athenian.
\regular - JI retuning, used by the Athenian and Promethean implementations.
\sagji - common code for Sagittal with just intonation.
\"sag60" - ratios mapped to 60-equal.
\"sag72" - ratios mapped to 72-equal.
\"sagji224" - Athenian accidentals but consistently applied according to 224-equal.
\"sagji60" - just intonation with accidentals for 60-equal.
\"sagji72" - just intonation with accidentals for 72-equal.
\trojan - common code for Trojan notations of JI.
\"trojan60" - just intonation rounded off to 60-EDO.
\"trojan72" - just intonation rounded off to 72-EDO.
Note: as the original code is not very DRY-ish, not namespaced nor modularized, I took the approach of defining commands for loading each of the original files. This way the original functionality is maintained with a minimum of fuss. If anybody feels like improving the API, please do so! - Sharon Rosner
- fig6.ly - another Sagittal example.
- harmonics.ly - the harmonic series in Extended Helmholtz-Ellis Pitch Notation.
- ratios.ly - example of JI duplicating the Sagittal paper.
- subharmonics.ly - another Extended Helmholtz-Ellis Pitch Notation example matching one of the defining papers.
addmts.py, addmts.py3 - Retune output MIDI files to use the MIDI Tuning Standard.
