• Add an editing interface: The aim of this project is to be wiki-like where anybody could fix mistakes or add new scores.
  • Add a booklet creation interface: Help with the preparation of chant booklets is a very demanded feature.
  • Clean the code and publish it.
  • Define a format for booklets and complex scores: there is already Andrew’s mgabc format but it’s using the <sc> tag for the gabc parts, which is a valid gabc tag for small-caps. We also need a way to deal with the cases where some notated part have a big initial while other don’t. Etc.

    Will you be adding a search box? I like that you have everything organized, but perhaps someone might not know where to look for a specific text. Also, there are several texts that don’t really fit in any of the categories you have. Pater Noster (in its various settings) for instance, or the various Gloria Patri in their tones.

      Let me add my voice to Benjamin’s as regards the Pater Noster and other chants of the Order of Mass.

      • | Permalink

        Which categories would you add for these?

        • | Permalink

          I would be glad to have a category “Cantus in ordine missæ occurentes” like in the Graduale Romanum (Solesmes, 1979, pp. 798 ss.) and another one “Præfationes in tono solemni” like in the Ordo Missæ in cantu (Solesmes, 1995, pp. 19 ss.).

      YES. It is a must to have a search box.

        I see mentions of a “search box” in 2013 and 2017. Here is a a useful tip:

        Google automatically indexes websites like GregoBase. If I want to specifically search just this site for “Pater Noster”, the Google search term is as follows: “Pater Noster”

        Here is a corresponding link:“Pater+Noster”

    It would be nice if you could have links on the individual chants to other chants nearby from the same book or at least a link to the source.php that scrolls down to the page that it is from.

    • | Permalink

      Now there is a link to the previous and next chant next to the source image.
      You can also browse through the source images and add chants from there.

    It also might be nice to be able to have tags, so you could tag chants for a certain feast with the feast, and then if an offertory or something is used for two occasions it could be tagged with both.

    Perhaps it would help if there was a button for non-GABC-educated types to note that there seems to be a problem with a score and give a description of the problem that an experienced GABCer can then look at and repair. That way you can have tons of non-GABCers proof-reading texts, leaving GABCers the time to go create scores etc.

    Is there any interest in uploading historical sources of chant? I’m thinking of not only the Ratisbon Gradual and the Medicea, but even medieval manuscript sources. It may be worthwhile also to get in touch with the folks at the CANTUS database ( to see if there is any interest in linking this database to theirs and vice versa, or even some collaboration.

      I think any source is worth it… if somebody wants to retranscribe it…

    Is it possible to order scores according to the calendar, either “de tempore” or “sanctis”?
    Perhaps when I add a new score I can put it in the appropriate place on the calendar. Is this possible?

    Sorry for my bad English.

    Could you add the Dominican Processionarium to the list of sources? It has some interesting chants not easily found elsewhere, particularly for the Officium Defunctorum such as the antiphon Clementissime.
    You can download it at (as you probably know.)

    Thank you. Another Dominican request: could you please include among the sources the Officium Hebdomadæ Sanctæ ( as it contains some unique chants – e.g. the Dominican version of “Ave Rex Noster” sung at the entrance to the Church on Palm Sunday. Thank you. – Martin OP

    There are two different Alleluias with the incipit Laudate Dominum. In the database, one of them is only available in the Dominican version and the other only in the Solesmes version. I am looking for the Solesmes version of the Alleluia Laudate Dominum which is currently only available in the Dominican version, namely the Alleluia for the 5th Sunday of Ordinary Time with the text “Laudate Dominum, omnes gentes : et collaudate eut, omnes populi”. Could this be added?

    For a nicer user experience, would it be possible to have the same complete alphabetic row of incipits repeated above each page of individual index pages?
    The result like this:
    (no incipit) A B C D E F G H I etc.

    Hello amazing Gregorio people,
    I’m a regular user of the database and have tried to register several times but didn’t work, have no idea what to do.

    Today I’m preparing the booklet for this coming Sunday liturgy O.T. XIII B, and the Maginificat antiphon taken from OP Antiphonarium Gillet, NON ENIM MISIT DEUS FILIUM…. has the wrong clef line, should be (c3) instead of (c4).

    May God bless you abundantly for your magnificent project. Many thanks.

    Several asks:

    * Add the source “Variae preces” (Solesmes 1892) – available here:

    * Add Rhythmus, Prosa and Tropa as usages

    * Some curating of tags (e.g., standardize capitalization and format) would be helpful at this point and enable tagging to grow

    Is it possible to add the two volumes of the Antiphonarium Sacri Ordinis Praedicatorum of Jandel (published 1863) to the sources? They contain a lot of chants difficult to find elsewhere, a number of which are referred to (but not actually reprinted) in the modern Proprium of the Order. These include especially the extended responsories, which were an important feature of First Vespers in the Dominican use. ( I have already transcribed a couple, but I had to submit them as “no source”. The pdf of the Antiphonal can be found at and ) Thanks for providing this magnificent service, GregoBase!
