As you read in Fr. Longenecker’s pastor’s letter from Oct. 23, 2022, we will be slowly learning some additional parts of the Mass in Latin.  Please read his letter again HERE. Beginning the weekend of Oct. 30, and only at the 10:30am Solemn Mass, we will sing the Gloria in Latin from Mass VIII, also known as the Missa de Angelis, or Mass of the Angels.  The liturgy at the 5:00 p.m. Masses on Saturday and Sunday will retain the Gloria in English, with the rest of the liturgy at those two Masses remaining as it currently is.
The tune for this Gloria is already known to you as we have sung it before in English.  The Mass from which this Gloria is taken is believed to date from as early as the 9th century. It is a plainsong Mass, designed to be sung in unison. We will sing this particular Gloria until the First Sunday of Advent, when the Gloria is then omitted as it is not sung during that season.
In order to help you more easily learn it, we are offering the following two links.  The first link is to a video musical score of the setting, with the text of the Gloria sung unaccompanied.  Here is that link:
The second link is to a video of a choir singing the Gloria with organ accompaniment. Here is that link:
Please take some time to listen to and review the recordings at these two links.  This will help you become more familiar with the Gloria from the Missa de Angelis and assist you to more easily sing the Gloria at Mass.  Feel free to just listen to the choirs and cantors at OLR sing the Gloria, if you need to do that, and then join in when you are ready.
Thank you for your patience and cooperation as we broaden our musical and liturgical repertoire, to the honor and glory of God through our historic Catholic faith and practice.
