How to participate?

In order to participate, you need to register or login.

What can I do?

  • Proofcheck. If there are no mistakes in a score, click the button “Proofread by Me”. If you spot some, edit the score and fix them or ask somebody to fix it for you. All changes can be undone so don’t be afraid of making mistakes, they all can be fixed losslessly.
  • Add scores. If you don’t know where to start, just go through the sources with images and start encoding.

Description of the fields

  • Score: the gabc code for the chant. If necessary you can add GABC or TeX sections (for some more complex chants – see exemples).
  • Hymn verses: for hymns where the music is exactly the same along the verses, only the first verse should be in the “Score” field. Following verses are to be put in this field (either GABC for music or TeX for textual version).
  • Incipit: speaks by itself.
  • Version: sometimes a chant exists in different versions. The versions currently used are “Vatican” and “Solesmes” according to the presence of rhythmic signs.
  • Usage: also called “office part”.
  • Mode: should be a number or “p” for the “Tonus Peregrinus”. The “ending” field is used to put the ending according to Solesmes classification.
  • Commentary: will be placed at the top right of the score (see Kyrie VIII or Tota pulchra es, for instance).
  • Initial style: choose whether to have a 1 or 2 lines initial or no initial at all. Warning: for 2-lines initial, you’ll need to specify the first 2 line breaks.
  • Original transcriber: use this field if you’re adding a file transcribed by somebody else.
  • Sources: “sequence” means the order on the page, “extent” on how many pages does it extend. If you want to add from a source that’s not in the list, just ask it to be added.

    I have many GABC files of antiphons from the recently published Antiphonale Romanum II however I was wondering if there would be any copyright issue with making these available on this website? If not, I would be happy to share them.

    • | Permalink

      There have been lengthy discussions about the copyright questions (see this thread, for instance) and the general consensus is that the books are copyrighted but not the melodies, except for newly composed ones but there aren’t many of them.

    Thank you for this web-page. It’s really amazing.

    I want to contribute with the “Angelus Domini nuntiavit Mariae”, in a version of Dom Charpentier OSB, that you can hear in this video:

    I have the GABC code but I don’t have the source. ¿What can I do?

    Best regards and thank you again for this web. I love it!

      I guess your source is The Traditional Roman Hymnal (2000). No idea what their source was… There is a short essay on gregorian chant written by “Dom Louis Charpentier, moine bénédictin” in 1929. If that one is the author, it might be not public domain… One would have to investigate about the year of death of that person 😉

    Hi all!
    I added two files (Veni, veni, Emmanuel & Resonet in laudibus) today.
    I beg your pardon for possible mistakes, and, if possible, your help to review and your commentaries. I’m new with Gregorio Editor, but, very interested in give some help.

    Is it possible to add the header “centering-scheme: latin;” as a default for each GABC file, or at least add that header when processing the GABC into PDF? That would improve the clarity of the PDFs, which some musicians use directly in choir materials.

    • | Permalink

      As far as I know, this is the default behaviour… Where is it not working that way?

      • Richard Chonak

        I was looking at a printed sheet made from a Gregobase PDF file. Perhaps it was made before the current centering rule was installed. Thank you!

    Would it be possible to add Cantus Varii (1902) as a source? The full name is Cantus Varii In Usu Apud Nostrates Ab Origine Ordinis, Aliaque Carmina In Decursu Sæculorum Pie Usu Parta. I can provide a scan.

    Where can one find the list of pages/images that have not been transcribed? I’ve been going through doing the “pleasefix” list as I am able, and I’d like to continue to move this forward. I made myself a commitment of doing at least one chant per day!

    Feature suggestion: should the proofread flag be reset when there are edits to the chant?

    Can you add the {multicols} package in your include section for TeX? That’ll really help for those multi-column texts that appear under certain chant scores.

    I’d like to add scores from the Cistercian Hymnarium and Antiphonale. Pictures of the books can be found on so there shouldn’t be copyright issues, right? Can those two books be added to the sources list?

    Can you add the roman numbers i-viij to be chosen as mode?

      You’re welcome 😉 what’s the difference between these and 1-8 ?

        In the psalmodie the ending of the second line of each verse is different. E.g. vij. T. descends in the end, whereas 7. T. rises on the last note.

        • | Permalink

          That’s going to get confusing since some books use Roman figures for the regular tones too…

    Could we perhaps rename the “Praefationes in tono solemni” category into simply “Praefationes”? I intend to add a number of prefaces in near future, both solemn & simple and don’t really see a need for them to be that separate.

    For ‘Jesu Dulcis Memoria’ I have a plainsong copy which has ‘Dans vera CORDI gaudia’. The versions on here have ‘Dans vera CORDIS gaudia’. Can anyone help with this reason and if I need to change it on my copy? Thanks

      IMHO “cordi” this is a mistake; I have too in this Gregorian Chant in the text “dans vera cordis gaudia” (Hymnus “Jesu dulcis memoria”, modus 1).

    What is the easiest way to find a chant which isn’t encoded? I suppose some books are all encoded so it would be good to know…

    • | Permalink

      I guess the easiest is to browse by source… If there’s only a limited amount of scores listed there, it might be useful to encode more of them…
      That said, they might be encoded already but missing the reference to that source…

    I am putting together a large print missal booklet. Many in our parish are older and cannot read the standard font size. Is there a way to alter your: (1) Font size (14pt or 26 pt) ; and (2) Font to something like Calibri or Arial (not narrow) so that they are legible to older pair of eyes? Illuminare editor has that feature, but unfortunately they have no PNG output, which is a huge bother. You’d have to PDF, screenshot, cut and paste to Word, resulting in blurriness. Please help.

      The GABC Transcription Tool’s ( PNG function works and produces clear results when pasted into Word.

      What I find to be easiest is to fiddle with the size settings in Illuminare, then copy the entire code into the transcription tool (make sure to select “show integrated GABC”). From there you can further manipulate the number on the “width” line if you want, then click download PNG.
