Easter Sunday is one of the few feast days that retained their traditional sequence after the purge following Trent. The 1570 Missale Romanum, however, tweaked the sequence Victimae paschali laudes a little, changing praecedet suos in Galilaeam into praecedet vos in Galilaeam. It also removed an entire verse, and added Amen and Alleluia at the end. The original verses of this sequence is laid out melodically in this manner A-B-B-C1-C2-C1-C2-D-D. It is the first D, which appears below (click on the image to open the file), that was removed.
Ut in omnibus laudetur Dominus.
