A Wonderful Website for learning the Proper Chants for the Sundays

Here is the wonderful website for the Propers: http://isaacjogues.org/chants/

Now you may ask...

"What are 'the Propers" in the Mass?" -That is a good question.

Here is the answer: The Proper of the Mass, strictly speaking, consists of the Introit, Gradual, Alleluia or Tract, Sequence, Offertory, and Communion.

The Ordinaries are as follows:

(The following parts, if not sung by the whole congregation, are traditionally sung by a choir)

1. Kyrie eleison ("Lord, have mercy")
2. Gloria ("Glory to God in the highest")
3. Credo ("I believe in one God"), the Nicene Creed
4. Sanctus ("Holy, Holy, Holy"), the second part of which, beginning with the word "Benedictus" ("Blessed is he"), was often sung separately after the consecration, if the setting was long. (See Benedictus for other chants beginning with that word.)
5. Agnus Dei ("Lamb of God")
