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.
