For the brave there are also complete worksheets, i.e. all my rough gly documents with transcribed scores compiled to pdf, without any structuring (except of division into files and score ids) and without even the minimal care taken of beauty.


2016-03-06 Worksheets made available.

2016-01-24 Psalter: all four Sundays.

2016-01-21 Psalter: remaining pieces for ferias of week IV.

2016-01-18 Psalter: remaining pieces for ferias of week III.

2016-01-17 Psalter: remaining pieces for ferias of week II.

2016-01-14 Psalter: antiphons for Gospel canticles, officium lectionis and hora media as well as short responsories. Please note that some of the repeated chants (among others the responsories) are now wrongly assigned to days of weeks II and IV. This is due to the way how the build script works and it will be fixed as soon as week II is finished.

2016-01-09 Psalter: antiphons for psalms of ferial Lauds and Vespers completed. (The few missing ones are not easily available to me and will be addressed later.)

2016-01-07 First version of the psalter. Contains antiphons for ferial vespers and lauds, excepting the 4th week and a few bits of weeks 1-3


This is an attempt to assemble an antiphonal for Liturgia horarum (the Roman Catholic post-Vatican II Divine Office in Latin) following the (now outdated) 1983 Ordo cantus officii. It’s currently a work in progress, moving towards the distant goal in a slow pace.

As hymns and invitatories have been published in the Liber Hymnarius, this project only deals with antiphons and short responsories.


Why would one assemble an antiphonal (that’s quite a lot of work!) following an outdated liturgical order?

First, I hope preparation of a (full) official edition of a Roman antiphonal is in progress and I don’t want to damage the publisher by providing the same content (though, of course, in worse quality typographical, musicological etc., but) for free. In the meantime I find it just fine to follow the 1983 order, at least for private prayer of the laity.

Second, I find it of historical value to have access to the antiphonal “as it was” or rather “as it could have been” (if anyone dared to assemble it earlier) in the period 1983-2015.

Sources / How to contribute

You can fork antiphonale83 at github and modify it for your own purposes or even contribute to it by transcribing some of the missing chants.
