Chant Books for the Congregation
The starting place for congregational Latin chant is any major Catholic hymnal-see the Mass Ordinary, Order of Mass, and easier hymns and antiphons. Published collections of congregational chant:
Iubilate Deo ("Shout to God"), Libreria Editrice Vaticana, expanded edition, 1987.The entire order of Mass for congregational singing in Latin, including all the responses and some settings of the Ordinary, plus a few other miscellaneous chants. The idealistic wish of Pope Paul VI was that this would become the core repertoire known by Catholic congregations around the world.
Liber Cantualis ("book of chant"), Solesmes, 1978. T he Order of Mass, seven chant Ordinaries, the Mass for the Dead, the four sequences of the postconciliar liturgy, and various antiphons and hymns for seasons of the liturgical year.
Kyriale Simplex ("simple Kyriale"), Libreria Editrice Vaticana, 1965. A kyriale is a collection of Mass ordinaries. An interesting collection of Mass ordinaries, astutely drawn from non-Roman traditions of Latin chant (e.g., Mozarabic, Ambrosian) to provide the most singable congregational Mass settings.
Chant Books for the Choir
Graduale Romanum ("Roman gradual"), Solesmes, 1974. A large book of Mass propers-those difficult masterpieces of the chant repertoire-with the Order of Mass and Mass ordinaries also included.
Gregorian Missal for Sundays, Solesmes, 1990. English translations next to each Latin chant, excerpted from the Graduale Romanum to include all the Sundays and feastdays. Other liturgical texts (e.g. presidential prayers, eucharistic prayers) are also included in English.
Graduale Triplex ("triple gradual"), Solesmes, 1979. Identical to the 1974 Graduale Romanum, but with early lineless neumes written in above and below each chant melody (hence the "triple" in the title, with a total of three notations for each melody). A book for specialists, but some study of it will be helpful to understand how to interpret and convey the Latin text in chants of all levels of difficulty.
Easier Chant Books for the Choir
Alongside any major Catholic hymnal, which has Latin congregational chant which can also be sung by the choir, here are some easier collections of chant for choir.
Graduale Simplex ("simple gradual"), Libreria Editrice Vaticana, 1975. Although intended for congregations, the scope of this collection and the fact that it is entirely in Latin makes it rather unusable for most congregations. In practical use, a handy fall-back when the choir is not able to learn the propers from the Graduale Romanum . Easy chants for Mass-entrance, Psalm, Gospel acclamation, offertory, and communion-with an easy antiphon and several pointed Psalm verses, for use at any Mass within a given season. The short, easy antiphons were taken from the Psalm antiphons of the Latin Liturgy of the Hours.
Cantus Selecti ("selected chants"), Solesmes, 1989. A large excerpt from the 1949 version. A broad selection of chants for every season and for occasions such as Benediction of the Blessed Sacrament or devotions to the Blessed Virgin Mary-hymns, sequences, tropes, and antiphons. A choir able to sing a repertoire this extensive would probably be ready to make use instead of the Graduale Romanum.
Psallite Domino: Canti per la Messa ("Sing to the Lord: Chants for Mass"), Solesmes, 1997. An excerpt from the Graduale Simplex , a very useful smaller collection for choir. The text of each chant is translated into Italian. It has recently been reissued in expanded form.
Chant Books for the Liturgy of the Hours
Antiphonale Romanum ("Roman antiphoner"), 1912. The preconciliar Roman Office, from which the Psalm antiphons were taken for the Graduale Simplex after Vatican II. It has not yet been revised for the reformed Roman Office, with the exception of the Liber Hymnarius (see below).
Antiphonale Monasticum ("monastic antiphoner"), Solesmes, 1934. The preconciliar Benedictine Office, with much overlap with the Roman office (although the melodies have been corrected to be more accurate).
Liber Hymnarius ("hymn book"), Solesmes, 1983. All the Latin Office hymns for the revised Liturgy of the Hours in both Roman and monastic form, with texts and melodies corrected as called for by Vatican II. The foreword is highly important for explaining the revised four-line notation and the subtle rhythmic interpretation intended by it.
Antiphonale Monasticum, Solesmes, 2005 and since. Three of the four projected volumes of the revised monastic Office have appeared so far. A wealth of resources to draw on for various ways of celebrating the monastic Office. Unfortunately, rhythmic signs (e.g., the horizontal episema) are not included, although these were part of the revised notation presented in the 1983 Liber Hymnarius.
