Are the Solesmes editions in conformity with the official edition?

Jeff Ostrowski · May 24, 2020

HAVE OFTEN said that only a lunatic would try to restore the official “pure” Editio Vaticana since the “Dom Mocquereau” rhythm has reigned supreme for 110 years. For one thing, there’s ambiguity about locating the mora vocis for a Virga which “commands” the notes around it. To learn more about that ambiguity, visit this page and scroll down to the section marked Invisible White Notes—then look for the section which speaks of an “unforgivable mistake.” Moreover, even the “pure” Editio Vaticana editions (inexplicably) don’t adhere to the official rhythm.

The first Alleluia from this morning is a case in point.

We begin with the “Dom Mocquereau” rhythm—which has not changed since 1908. Notice how they ignore the morae vocis where red arrows point:

The 1917 Schwann ought to adhere to the official rhythm. However, they fail to hold the “blue arrow” notes, which should be elongated since they are part of a neume. It sounds beautiful as they mark it, but it’s technically wrong:

Dr. Francis Xavier Mathias gets an A+ because he adheres perfectly to the official rhythm:

The 1953 Schwann editors (Abbot Urbanus Bomm, Karl Gustav Fellerer, and Msgr. Johannes Overath) claim to follow the “pure” Editio Vaticana rhythm—yet, they inexplicably tell the singer to ignore the moræ vocis…which is quite surprising!

As usual, the Nova Organi Harmonia matches the “pure” Editio Vaticana rhythm perfectly, although they rely on the organist to hold the “blue arrow” notes; that is to say, their method is to mark the morae with a single dot, even when the neume is to be elongated:

We end up right where we began: While it’s true the Solesmes editions contradict the Vaticana rhythm (and technically are not allowed), there is no edition that conforms perfectly to the official rhythm!

PDF Download • Trinity Sunday (22 pages)

Feel free to download this Organ Accompaniment Booklet for Trinity Sunday (Second Vespers). Notice how the modes progress by number. Psalm 1 is mode 1; Psalm 2 is mode 2; Psalm 3 is mode 3; Psalm 4 is mode 4; Psalm 5 is mode 5. I am told by an expert that other feasts (such as Corpus Christi) are likewise organized by mode, and it’s called a “numerical office.”

10 June 2022 • “Official” rhythm of plainsong

I continue to search for the most beautiful way to present the “pure” Editio Vaticana scores. (Technically, the “pure” rhythm of the official edition is what everyone is supposed to use.) You can download my latest attempt, which is the Introit for this coming Sunday: Feast of the Most Holy Trinity. Because this is not an ancient feast, the Introit had to be adapted (perhaps around 750AD). Prior Johner says the adaptation is “not an entirely happy one.”

Random Quote

By far, the event that caused the biggest increase in requests for indults from the morning Mass requirement was the Second World War. The unusual requirements of providing Mass during wartime led to some unique legislation accommodating the time of Mass. Already in 1940, Pope Pius XII issued a motu proprio addressing the situation of holding Mass in countries where a “Black-out” had been ordered.
