Among those compositions, is the Adoro Te Devote, Pange Lingua, Sacris Solemnis and Verbum Supernum. Sadly, not as universally popular is the Sequence of the Mass of Corpus Christi Lauda Sion Salvatorem. Indeed, perhaps the only part of it that has entered the popular repertoire are the few lines Ecce Panis Angelorum, factus cibus viatorum: vere panis filiorum, non mittendus canibus that have frequently been set to music independently of the rest of the Sequence.
This is also true in the case of the Pange Lingua, which, although the full hymn is memorably used on Holy Thursday, the last two verses form the Benediction hymn Tantum Ergo, which is a stock favourite. Likewise, in Sacris Solemnis, the sixth verse gives us the famous Panis Angelicus, and the hymn of Benediction O Salutaris is found towards the end of Verbum Supernum.
The second video clip is the popular and most common version of Ecce Panis Angelorum, while the third is the setting by the famed Don Lorenzo Perosi.
In speaking of the Sequences of the Roman Missal, the Catholic Encyclopedia says: Each of the five has its own special beauty; but the "Lauda Sion" is peculiar in its combination of rhythmic flow, dogmatic precision, phraseal condensation."
In common with the other Sequences, Lauda Sion is double strophed. That is, it repeats the same melody in two lines before moving to another melody for the next two lines. This doubled strophing, or strophe and counter-strophe pattern that sets the Sequence apart from the hymn. Effectively, each strophe/counter-strophe would have been sung alternately by the two liturgical choirs. Such double strophing is found frequently in the Books of the Old Testament, particularly in the non-Major Prophetic Books, Hosea, Amos and Job being particular examples.
