At what seasons “Alleluia” must be said.
From the holy feast of Easter until Whitsuntide, let “Alleluia” be said without intermission, as well with the psalms, as with the responsories. From Whitsuntide till the beginning of Lent, let it be said at all the Night-Offices, with the six last psalms only. But on every Sunday out of Lent, let the Canticles, Lauds, Prime, Tierce, Sext and None, be said with “Alleluia.” Let Even-song, however, be said with antiphons. Let the responsories never be said with “Alleluia,” except from Easter till Whitsuntide.
