Just as its companion motet above, this motet’s textual underlay is a minefield of guessing games. The chant source is the traditional alleluia for Easter Sunday, easily found in the Liber Usualis, Graduale, Romanum, Graduale Pataviense, etc. I have documented those places where variances from the Formschneider were made. Some of these phrases are incredibly long, requiring either instrumental doubling or multiple voices for covering individual breaths.
Alleluia. Pascha nostrum immolatus est Christus. Alleluia.
Alleluia. Christ, our Passover, is sacrificed for us. Alleluia.
