If you are looking for something quick and easy, you might try this site.

I think we forget that not everyone knows all the "best things" to do....
Here's a quick roadmap for beginners.


===============================

The "Four Hymn Slots":


Opening/Procession/Gathering Song:

Best option: The Introit chant assigned for the day, from the Graduale Romanum
-Can be found also in the Gregorian Missal.
-Can be found (easiest solution) at http://isaacjogues.org/

Second Best Option: A seasonal introit from the Graduale Simplex
-to my knowledge, this is not available online

Third Best Option: An English setting of the day's Introit chant, in a style derived from chant
-Adam Bartlett's Simple English Propers at http://musicasacra.com/simple-propers-of-the-mass-ordinary-form/
-One of several other similar projects (I'm sure others will post to them below)

Fourth best option: An English setting of the day's Introit chant, in a traditionally sacred style not derived from chant
-Christopher Tietze's Introit hymns
-other similar things, which others may mention in the comments below

Fifth option: A traditional hymn which mirrors closely the Introit text.

Sixth option: A contemporary, but still sacred in nature, hymn or song which closely mirrors the day's Introit text

Sixth option: A traditional hymn which has, maybe, something to do with the lectionary readings, and isn't heretical

Seventh option: A contemporary, but still sacred in nature, hymn or song which has, maybe, something to do with the lectionary readings, and isn't heretical or stupid



At the Offertory:
-See options above, with the exception that Tietze's work is only for Introits.


At Communion:
-See options above, with the same exception


Recessional/Exit/Song for Sending Forth/ Closing Number/Grand Finale:

First option: Instrumental. Usually organ.

Second Options:
-Traditional hymn, preferably having something to do with the Feast, the Readings, our mission as Christians, or (always appropriate) the Blessed Mother.
-silence

Third option:
-Contemporary song or hymn, preferably having to do with the Feast, the Readings, our mission as Christians, or (always appropriate) the Blessed Mother. Be sure to filter for heresy and stupidity.
==================

The Responsorial Psalm:

Two options, which I consider of equal value, but others may disagree:
1. The Gradual chant for the day, from the Graduale Romanum (see above for online resources)
2. A chant setting of the Lectionary Responsorial Psalm, from a resource like Chabanel Psalms http://chabanelpsalms.org/year_A/

Other options:
-A setting of the Lectionary Responsorial Psalm from a resource like "Respond and Acclaim" (OCP)
-A setting of the Lectionary Responsorial Psalm from a resource like "Psalms for the Church Year" (GIA)

Be sure to avoid:
-Paraphrases of the psalm.
-Songs loosely based on the psalm.
-Songs completely unrelated to the psalm, chosen for no apparent reason.

====================
The Gospel Acclamation:

First best option:
-The Alleluia (most of the year) or the Tract (in Lent) from the Graduale Romanum (see above for online resources)

Second best option:
-A chant setting of the Gospel Acclamation verse (from the Lectionary) along with "Alleluia" (when appropriate) as found in resources like the Garnier Alleluia http://garnieralleluias.org/

Third best option:
The "Gospel Acclamation" as found in a good Mass setting. Make sure the words are right.

Do be sure to avoid:
-singing "alleluia" in Lent
-singing randomly selected songs prior to the Gospel




==================
The Mass Ordinary
(What you might know as "the Mass Parts" -- the things usually sung every week, like the Kyrie, the Gloria, the Holy, the Memorial Acclamation, the Amen, etc....)

Best option:
The Gregorian Mass settings, as found in an official Kyriale.
Online at:
http://www.antoinedanielmass.org/kyriale/

Second best option (not available until Advent):
The ICEL chants of the new translation

Third best option:
The least awful Mass setting that your congregation already knows, as you wait until Advent to implement the new ICEL chants.


====================



I hope the roadmap helps.

In re the Introit, why would a seasonal introit from the Simplex be better than an English setting of the the proper text for the day? It's not in keeping with the GIRM, which lists the first option as "(1) the antiphon from the Roman Missal or the Psalm from the Roman Gradual as set to music there or in another musical setting."

The CCCB provides suggestions for music from the CBWIII in the documents called "Music for Sunday Assembly" for years A, B and C. You can download Year A here: http://www.cccb.ca/site/Files/CBW_III_Music_suggestions_YrA.html

You can also download Year A, B and C and other documents from here: http://www.cccb.ca/site/eng/commissions-committees-and-aboriginal-council/sectoral-commissions/liturgy-and-the-sacraments-english-sector/documents

Mark K - thanks for those links.

Others - The parish currently sings everything either out of the CBWIII, Gather (GIA), and Rise Up and Sing (OCP) or this illegal photocopy thing called "Youth Ministry Choir Music", of which about 50% are pieces available through CCLI. I do not think that I have the resources available to print single-use music sheets with the music/chant of the day on them. (I've been told that there is no money to replace the 100-page songbooks with ones full of legal imprints, so I can't imagine they would want me to print off 100 song sheets for each Saturday Mass).

I want to introduce some "new" ancient music to the parish, but to do so at a rate more than 1 at a time would probably lead to a revolt. This parish actually sings, which is nice, except that they have a very limited repertoire. The parish does not even use a 'Mass setting' - the Ordinary is a hodge-podge of various settings that includes a Lord's Prayer in which everyone sings the embolism.

Thanks for the links - I'll get reading.
