I was wondering if anyone on the forum can translate French to English well enough to tell me who the author is of this Method of Plain Chant.
I believe the melody of the hymn to St. Paul was taken from this collection of Plain Chant. Although the hymn shows 1782 and the book cover is 1815, I believe it to be the same composer.
It does appear that Monseigneur de la Feuillee is the responsible party. I don't think this is the Louis Feuillee who pops up on internet searches, given that the publication is 1815 and he was dead by the middle of the 1700s, and based on the fact that nothing in Louis' biography suggests a musical bent or an ecclesiastical career.
I think 1815 is just the printing date [Chants grégoriens]. De la Feuillée. Méthode nouvelle pour apprendre parfaitement les règles du plain-chant. 1 volume in-12 reliure cuir. Poitiers, 1754. for sale : here
Yes, you're right. De la Feuillee didn't appear to have any musical background (in my cursory search) so the date wasn't the only support for my conjecture.
Our friend Jehan Boutte should be of help here - if he is tuned in. Curious that the hymn shown is a modern style hymn - not an example of plain-chant figure et musical as advertised on the title page. The tune itself is not bad but is rather unimaginative and predictable.
Feuillée (from feuille, leaf) is the leafy canopy used in religious processions or a camp latrine, as well as a not too uncommon name (ours is missing from both fr:WP dab and New Grove). Adam de la Halle wrote a Jeu de la feuillée; to go by the WP article he seems to be punning on folie.
Or the date of a new (enlarged) edition, with the original author's name retained as part of the title, as in Webster's Dictionary or Butler's Lives of the Saints.
