LOTH Ordo Cantus Officii acronym question

    Almost all the music presented includes, to the upper right of each example, the acronym “CAO” (followed by what I presume is a catalog number) which I have not found defined in the “Sigla in Indicibus Adhibita” at the end, or anywhere. If anyone knows, kindly fill me in? Many thanks.

    The abbreviations are listed on pp. 13-14 of the book (2015 edition); CAO stands for:

    R.J. Hesbert, Corpus antiphonalium Officii, vol. III, Invitatoria et Antiphonae; vol. IV, Responsoria, Versus, Hymni, et Varia, Rome: Herder, 1968-1970.

    how to quickly find chants referenced by CAO numbers:

    1. http://gregorianik.uni-regensburg.de/an/ allows filtering by CAO number

    2. Cantus IDs of chants included in CAO are usually (although not always) built by zero-left-padding to the six character length, so that e.g. CAO 3255 is https://cantusindex.org/id/003255 at CantusIndex

    I recently acquired a document online whose first page simply reads

    ORDO CANTUS OFFICII
    EDITIO CUM CANTO

    v.5 A.D. MMXXIV

    and whose pages 13 & 14 are Lauds and Vespers antiphons for the first week of Advent, thus my confusion. Thanks for clarifying!

    That'd be Jeorg Hudelmeier's pdf! I use it constantly and I'm happy more people are enjoying it.

    Since we're asking about acronyms, I've got a list here of the ones for sources in the document, but I don't know what all of them are (since I don't have the actual book). Would anyone be able to fill in the blanks here?

    AM: Antiphonale Monasticum 1934

    AR: Antiphonale Romanum 1912

    ARII: Antiphonale Romanum II 2009

    AS: ???

    AV: ???

    CAO: Corpus Antiphonalium Officii

    GS: Graduale Simplex 1975

    LHym: Liber Hymnarius 1983/2019

    Mil: ???

    NAT: In Nocte Nativitatis Domini 1936

    OHS: Ordo Hebdomadae Sanctae 1961

    OP: Dominican antiphonary 1933

    OCSO I/II: something Cistercian?

    PM: Psalterium Monasticum 1981

    PRM: Processionale Monasticum 1893

    Rom: ???

    RM: Liber Responsorialis 1895

    Sol: ???

    tr.man.: ???

    VP: Variae Preces 1892

    AS: Antiphonale Solesmense (Paris, 1935)

    Antiphonale Solesmense (Paris, 1935)


    But what is the difference between this and the AM which is technically the antiphonal of Solesmes used by everyone else?

    Because the Antiphonale Solesmense (1935) contains antiphons that the Antiphonale Monasticum (1934) does not. A few examples:

    Praeclara salutis (AS 842) for B. Mariae Virginis de Lourdes (February 11) [but also in AR 540]
    Illuxit dies (AS 855) for Ss. Perpetuae et Felicitas (March 7)
    Martyr et pontifex (AS 982) for S. Bonifatii (June 5)

    From what I noticed by quickly scanning OCO is that the references to AS are sparse and are limited to mostly the Proper of Saints (but I may be wrong...)

    So if I have this right:

    Mil: melody taken from the Milanese (i.e., Ambrosian) tradition
    Rom: melody taken from "old Roman" chant
    Sol: ancient melody adapted by Solesmes
    tr. man.: medieval antiphon lacking a CAO #
