Chant Wars: TeX vs LilyPond
The Gregorio project – GPL tools for typesetting Gregorian chant
Open‑source chant tool sparks TeX vs LilyPond showdown, priests and geeks sing its praises
TLDR: Gregorio is a free tool for writing and printing Gregorian chant, and its launch sparked a TeX vs LilyPond debate. Critics tout LilyPond’s reputation, while priests, veterans, and tinkerers celebrate Gregorio’s clean scores, GPL freedom, and a snappy online editor, with curious onlookers asking about Byzantine notation.
Gregorian chant just crashed into geek world with Gregorio, a free toolkit that lets you type chant in plain text and print gorgeous scores using TeX (a fancy document maker). It’s under a “shareable for everyone” license (GPLv3) and even has a playful namesake: an imaginary Latin verb, gregoriare, “to sing chant.”
But the choir didn’t stay in harmony. One of the loudest reactions turned this into Chant Wars: “Why TeX and not LilyPond?” LilyPond is a beloved open‑source music engraver, and its fans showed up fast, calling it the “gold standard” and asking for head‑to‑head comparisons, even linking LilyPond’s own chant features here. Meanwhile, church pros and longtime users hit back with lived experience: an Anglican priest cheered that this will make cleaner Sunday bulletins, and a veteran typesetter reminisced about using Gregorio 15 years ago to avoid those blurry bitmap music snippets.
There were side quests too: one curious voice asked about Byzantine notation (the chant cousin from the Eastern churches), and a helpful commenter dropped a faster, click‑and‑try web editor here for anyone who doesn’t want to wait for TeX to compile. The memes? “Singing in ASCII,” “hacker monks,” and a whole lot of “don’t start a holy war” energy. Verdict: ancient music, modern drama — and everyone’s humming.
