87. After the readings from the Old Testament, the hymn “Gloria in excelsis” is sung, the bells are rung in accordance with local custom, the collect is recited, and the celebration moves on to the readings from the New Testament. There is read an exhortation from the Apostle on Baptism as an insertion into Christ’s paschal mystery.
Then all stand and the priest intones the “Alleluia” three times, each time raising the pitch. The people repeat it after him. (Cf. Ceremonial of Bishops, 352)
Does your presider intone “Alleluia” as described here? The more usual practice is thus:
If it is necessary, the psalmist or cantor may sing the “Alleluia”, which the people then take up as an acclamation to be interspersed between the verses of psalm (118), which is so often cited by the Apostles in their Easter preaching (Cf. Acts 4:11-12; Mt 21:42; Mk 12:10; Lk 20:17). Finally the Resurrection of the Lord is proclaimed from the Gospel as the high point of the whole Liturgy of the Word. After the Gospel a homily is to be given, no matter how brief.
Thoughts? Even if brief?

Well, in most of the churches where I attended the Vigil, the use of the traditional Gregorian trifold Alleluia was normal.
Usually let a cantor intone the Alleluia, rising pitch as directed …
I don’t know if this would be ‘cricket’ for us Latin-rite folks, but I like the way our Eastern siblings always use the short Easter homily of St John Chrysostom. Less than a page in Byzantine Daily Worship, rousing, and the presider doesn’t need to come up with something new.
I also like the idea of the Patristic homily, which takes on the nature of prosody

Awesome! I will steal it (er, preach it) the next time I preach at the Vigil.
