NLM guest post by Jeffrey Ostrowski
The author believes that restoration of the Propers in the Ordinary Form can only be achieved by absolute consistency of use. Many versions of the Propers are needed to facilitate this noble goal. Our new publication is presented as a type of "missing link" for Sundays or Holy days when no other version of the Propers can be sung (due to sickness of the music director, lack of adequate practice time, or any other reason).
It probably would be accurate to think of this book "the Ordinary Form Rossini Propers."
