Dear gentlemen, while singing the hymn "Aeterne rex altissime" I noticed: Instead of "triumphum" it should be "(datur) t r i u m p h u s (gratiae)" https://gregorien.info/chant/id/282/13/de Aeterne rex altissime, redemptor et fidelium, quo mors soluta deperit, datur triumphus gratiae. Dr. Heinrich Bernhard Kraienhorst, Pastor Wallenhorst (Diocese of Osnabrück, Lower Saxony)
