The Pange lingua gloriosi ought to be sung in alternation (cantors-all or men-women); this becomes particularly acute when the people are used to intoning themselves only part of it and not really knowing the melody as well as they think, having learned it orally. But hopefully no one insists on going on to Tantum ergo when either one must wait briefly or return to the second verse… Some instruction may be needed; otherwise, more musically advanced parishes may choose a polyphonic setting of the text to conclude the hymn.
Remember that it is not especially Roman for the thurifers to ever walk backwards. It is also easier to walk the normal way. When arranging the altar of repose, think of your future selves; flowers do not belong right in front of the altar. While the ideal altar of repose is temporary, as splendid as it ought to be, and does not use a tabernacle, but rather a sort of urn, it must lock, and the altar of repose needs to be reasonably out of the way. A side altar must do for many of us, and it can be quite splendid as shown in another example from the Institute of Christ the King.
But should the Mandatum be done at all? It depends. Some pastors in the West (Europe and North America) are sensitive to not only not having ecclesiastical subordinates as does a bishop or religious superior, or at least the dean of a cathedral chapter, but that the otherwise natural replacement are children, not the men of the parish, and so they do not wish to touch the feet of the altar servers, at least the minors. Since most servers are boys, or at least will be some part of the contingent necessary for the Mandatum rite, then it is easy to justify omitting the rite. It is also optional. Now, most of this is optional as it is, but if one had to cut one thing from this week, it would be the Mandatum, if it meant preserving everything else including Vespers of Thursday and Friday.
Moving on to the stripping of the altars: my reading is that ps. 21 and its antiphon are sung recto tono, not with the chant from Good Friday’s Matins. The psalm need not be repeated, nor the repetition of antiphon delayed, if the carpet, some of the candlesticks, etc. are not removed promptly, so long as the ministers have finished removing the altar cloths and the major part of the work is completed.
More considerations on the Divine Office will follow, but I would strongly encourage you to sing, even recto tono, Vespers after the main liturgy on Thursday and Friday; on all three days of the Triduum, one could celebrate None beforehand, although this is not strictly required.
One does not need black falls for the legilia or covers for the missal. Everything is “naked” on this day. But what applies to purple folded chasubles applies to the black worn on this sacred day. The Good Friday celebrant’s chasuble should be even more splendid than usual if possible.
If you have adoration lasting into the night of Thursday, ending at midnight per the rubrics common to all variations of the Roman rite, then you will likely wish to change the candles and followers at the altar of repose before beginning the Mass of the Pre-Sanctified.
The choirmaster must work with the celebrant to give the right pitches for the unveiling of the cross. Try to roll with what he sings, not what you planned to sing.
Just as on Sunday and on Thursday, the music for the adoration covers the adoration itself. It need not extend beyond this, and should not, only to the extent that a chant should finish logically and polyphony should finish in its entirety, omitting subsequent chants or polyphonic settings. For example, one may end the Reproaches with one final “Popule meus,” one should repeat the antiphon Crucem tuam, and one should sing the (entire) Crux fidelis, but one need not sing all of the chants just to sing them, if adoration has concluded.
The books are clear: the people adore by genuflecting on both knees three times as they approach the single large crucifix placed on a cushion. Permission was given, admittedly, to pass down the communion rail a crucifix which essentially eliminates this creeping to the cross. But it happens once a year. It replaces communion on this day. This rite was broken in bits first in 1955, and in 1970, doing what Thomas Cranmer and his ilk wished to do but as it turns out from the inside. Unless there is an unusually large congregation (not realistic in most churches attached to the traditional rite and to the traditional Holy Week ceremonies), I would not recommend skipping the creeping of the cross in favor of the permission to move down the altar rail with a crucifix to be kissed by the faithful, but this requires coordination with ushers.
Should the people remove their shoes? I am in favor of this, and it may happen anyway, as they copy the clergy.
The rest of the rite is quite straightforward, so long as the Vexilla Regis begins only when the procession departs to return to the main altar. I hardly wish to touch the prayer for the Jews, but most clerics will probably use the 2007 prayer preceded by the genuflection as with the other prayers (keep in mind that this is the original pre-Carolingian practice).
Make sure you know that the tool used to light and extinguish candles is brought to the altar of repose for the actual Mass of the Presanctified when candles are lit at the same time that the cross is adored and, importantly, that it is returned to the sacristy before Tenebrae.
The triple candle is not easy to make. I do not make it myself. Various ways of heating the wax to twist three candles together including a sous-vide machine and using a weight system may work. I find that it is most in the spirit of things to have three candles in one, as opposed to three candles in a candelabra attached to a pole.
If possible, I encourage using a different dalmatic than the one for the Mass as seen here in photos from Saint Mary’s Oratory in Wausau, Wisconsin. A nice lampas could work too. The priest’s chasuble for the vigil itself is also especially striking.
For the procession and the blessing of the font, it may be necessary to begin the tract as the celebrant prepares and the candle is removed. Otherwise, the tract will be so long with the ministers left waiting at the font. If the Palestrina setting is sung, there is a second part in polyphony, or one may sing the chant.
The Litany is tricky. First, it seems that it may be started as the celebrant begins to process from the baptistry; he need not be prostrating at this point, if he blessed the font. Otherwise, it makes sense to wait, when the font is not blessed.
All of the invocations are doubled, that is, from “Pater de caelis…miserere nobis” to “Santa Maria, ora pro nobis” all the way to the end of the Litany, with the invocations “Ut…te rogamus audi nos” (possibly — probably — excluding the Agnus Dei; see below). This is entirely foreign to anyone used to the 1960 or 1970 rubrics. I find it best for cantors to sing and to reply to themselves, that is, they sing all of the first “Santa Maria, ora pro nobis” by themselves, and so on and so forth. Then the people only reply to the second invocation. Why? In part, to not mess up and to stay together. The chant books have breath marks omitted from missals in the last set, and then the people clearly hear the plural invocations of the saints (some pairs of saints invoked together, the “All ye…” concluding each section…).
Further, the cantors alone should restart at “Agnus Dei…” and in my ideal world, they sing until “Parce nobis, Domine” etc. The last invocation is not sung with the same melody as in Mass XVIII, so it needs to be taught to the congregation ahead of Holy Week. (One can send links via email newsletters and the various apps for parish communications; it might be helpful to do a series with recordings. A handful of parishioners in the pews who are prepared can make a difference.) I cannot tell from the rubrics or from the ceremonials if the Agnus Dei strophes or the “Christe, audi nos”/“Christe, exaudi nos” are also doubled. To me, I think that they logically are not, but everything else is, so it feels inconsistent. In any case, some instruction on the chant of the Litany is needed.
The pitch will almost inevitably drop when doubling. I recommend starting on B flat or at least A and to correct the falling pitch at each new set (certainly by “Peccatores”…).
For the solemn Alleluia, the choirmaster must work with the celebrant to give the right pitches. Try to roll with what he sings, not what you planned to sing. In this case, feel free to intone for the repetition if the celebrant takes you too high such that the next two, or even the current one, are out of range. With this in mind, ideally, the bulk of tracts are sung in one key, but the verse and final tract follow the last pitch of the final Alleluia, and so they may be in a different key if you choose a more comfortable key for the others.
I personally prefer to omit the Marian antiphon, even if on Saturday there is not much congregational singing to do. In a way, Christ is not yet risen! Also, recessing to organ music is much easier after singing for three to four hours, and besides, the antiphon comes back after Compline, not Vespers, and we should respect this even outside of obligatory prayer of the office in choir.
We will conclude the series with Tenebrae and the Divine Office.
